Default 5-4-18 recommendation needed

So, block is off for line bore and cleaning. I'm still torn between 393, 408 or 427 for the rotating assembly. But where I'm lost is the ancillary equipment. Flywheel, clutch, starter, dampener, bellhousing.

What I know for sure is the following. 500-600 hp, tko600, 0 (zero) balance rotating assembly. I'd like sfi approved parts, if possible.

Anything else I need to know? Recommended parts anyone?

I'm partial to aluminum flywheels. From what I read, Quicktime bell housings are high quality. I don't have any personal experience with one though.
Post a photo of the short block when you have it finished!

Quicktime makes a very high quality bell housing. I have had both the non-SFI and the SFI rated bell housing from them. Both fit well and typically they do not require a lot of dialing in. The flange on the SFI rated bell housing is more robust than the non-SFI rated one.

Those are all good sites in that list Brian and I use them all from time to time. I still use the free part of Photo Bucket once in a while but I like the others more.

Default Change in plans

So, I was looking at about 4 grand more, and a probability of NOT getting the car drivable by this fall, as I had hoped (unexpected expenses). I remembered a thread here where the advice given was to get the car running, then upgrade as time and money allow. I came across a 408w shortblock, newly built, forged crank, etc, but it's a 2 day trip (local pickup only). Back on Craigslist, I come across a complete, carb to oil pan, 351w with 2 hours run time. All parts in it are top shelf. Ported heads, roller valve train, forged pistons at 10.8:1. Ill be posting more as I crack in to it and have a peak. Anyone know the balance factor I'll be needing for the flywheel?

All 351W that are externally balanced, use a 28oz weight. Make sure the front balancer matches.

Thanks Larry, I'm on the hunt for a flywheel now.

The seller claims that the heads are maxed out for flow in factory castings. He was running an iron 4 bbl intake, I'll be replacing that.

I have a Price dual quad manifold topped with 390 holleys. Will it work well with this setup? Or should I look for a single carb combo?

Current plan is to continue the 408w build, so I'll also need an intake there too.

I like multiple carb setups as you know. It seems to me that Price casts their intakes with extra material so they can be ported up or down, depending what heads are used. You can check with them to be sure of fitment. Price Motorsport
As far as working, I don't see any reason they wouldn't work, though they'll probably need jetting to suit. FYI, they'll need balancer tops for the secondary's. They're available at a couple different Holley dealers. I never got around to buying them.

Default 7-7-18

So, you know the old saying "If you bought it on Craigslist, it MUST be good"? Me neither!!! So far, I've gotten the heads removed. EDIT TO CLARIFY -The engine I bought was advertised as having fullroller rockers, fully ported heads, and hydraulic roller lifters/cam. So far, that's not the case. Nor are the pistons a set of 11 or 12 to 1 forgings as was so enthusiastically described to me by the seller. So far I have comp cams roller TIP rockers, hydraulic non-roller lifters of unknown origin, and a set of heads for which any claims of flow are dubious at best.

Default Need cam help.

I decided to tear down and inspect, and it's not as bad as it could be. But its NOT what I thought I was buying. Rebuild is new, forged SRP pistons,looks like balancing, arp rod bolts, mild port job on D0OE castings. About the only thing I found down below that I questioned and will remedy is changing out the fully grooved main bearings for a set with solid bottom halves.

I need recommendations for cam, and to decide whether to run my price dual quad manifold topped with 390 cfm holleys, or get a air gap manifold with a single.

Engine has 9.6:1 compression. TKO 600, 3.55 rear. I want a hydraulic roller cam with a good lope to it, that is somewhat civilized. A few rough edges are ok.

Basically this engine is a way to fill the void NOW and sort out the rest of the car, then sell to another builder, once my 427w is finished.

If you are building a 408W call Lance at Craft Performance for the cam. I bought a 408 from him a few years back. Great sound, 530 hp. Good street manners. I sold the car and I gave the paperwork (cam card) to the new owner.

Default Latest progress.

So, here's the current situation. I ordered a Scat forged rotating assembly 47405. This kit yields 408 cubic inches, and comes with:
-4-inch stroke forged crank
-h-beam rods with 7/16 bolts
-Icon forged pistons. The kit specified a -25cc dish piston (I think), but Kevin over at Clegg engine was able to spec. -15cc dish slugs to get us up to a more ideal 10.5:1 compression ratio.
Also ordered:
-Scat SFI rated balancer
-157 tooth PRW flywheel weighing 24 pounds, also SFI rated.

For those wondering, Clegg engine is an engine shop that's only a couple miles from Kirkham"s facility in Utah, and they provide Kirkham builders with powerplants on the regular.

After being pointed in the same direction by both Kevin at Clegg and Wild Bill (my local guy), I opted for a hydraulic roller cam from Howards. P.N. 220275 yields 241 int. 247 ex. @.050" duration, and .581" int. And .608" ex. Lift with 1.6 ratio rockers. Lobe separation is 110, and intake c/l is 106.

I opted for a set of Howards Maximum Effort hydraulic rollers and a Howards billet timing set.

Anyone here used this cam? I'm really curious of what you think of it.

Dwight recommended getting the cam from Craft Performance. I agree. I have on of their Windsor based 427s with a Performer RPM air gap 572/582.

I'm surprised at the dish they have recommended for the pistons in your build. I'm running a 393 stroker with Vic Jr. heads and every calculator I could find to run around 10.2 compression came up with 22CC dish for my pistons. I would think with a 408 that the swept area would require a slightly larger dish to accomodate pump gas requirements?

Regardless, you're going to love the power in your engine. I tried several different carbs in mine and ended up with a 700 double pumper #4778-8 as the best option in the end. I'm running an Air Gap clone- a Weiand Stealth intake. I have a Holley 670 Street Avenger and a 770 also I'm looking to move if you're still looking for a carb. With my cam, they just weren't the right choice but they may work for your cam choice and intake better...

Very rarely are Fords (or any custom engine for that matter) optimal with shelf cams.

For the price of a custom, it's always a win/win. I've made 28 more peak hp and 10 more average hp by using my own grinds over shelf stuff.

That Howards cam is a typical "Chevy" grind.....6° duration split, with a 110 LSA, ground 4° advanced.

It's on the large side for a 408 as well, unless the cylinder heads are choked way down.

Default Cam choice.

Thanks for the heads up, Brent. I'll call you as soon as I'm through this latest medical crisis with my mom, (getting old sucks, avoid it at all costs). I was going to go with your cam originally, and you just sold me on the idea again. Are the howards lifters ok or should i send them back too?

"Max effort" lifters are very unnecessary. You need a regular "Street Series" lifter. Save yourself the money. Howards lifters are good, they're made by Morel.

Default In the same boat mate

Hi everyone. I’m new to the cobra scene and have started collecting all my parts.
I have an engine in mind (also a small block)
I’ve ordered a 351 Windsor dart block and was wondering if anyone has any experience with what they can handle?
I recently put a down payment on an IC Cars kit as I was really impressed with the way he goes about his builds and am excited to have a blast in it one day!
