Blown motor - which Long Block to buy?

[frankym]

cash burn, i'm open to selling. I have a ton of photos that you can find looking at old posts from me. I have had 3 superformances, the car we are talking about is a solid red, SPF #205. it has a retro fitted CSX rollbar to look like the original car. It has upgraded shocks. paint is pristine. I am open to selling it as is with a blown motor. car also has the oil accumulator setup plus halon. But I'm not interested in sacrificing it - I priced a brand new roller with these options and it is $57k. I would ask for 40k for it as is - but I am sure people would engage me and then offer 25k, which i have no interest in wasting time doing. It's almost always better to sell a completed car, but hey, if someone comes very very close to 40k, i'm a seller.

I am leaning toward keith craft on the motor for $12k, i can get the keith craft fully built 427R from carb to pan - it is a 4 bolt main dart sportman block with 585hp.

Sorry to hear of your issues. I have a Keith Craft 427 in my car and while I now know it is a very solid motor I would make sure I talked to them about the specifics of the build you want. My car has the 427w and it makes 592hp at 6600rpm. For the street it is not the ideal motor......lots of duration with my cam it sounds like a pulp wood truck until you get it over 2500rpms and then the power delivery is between 5000-7000rpm's. If that floats your boat then so be it but its not ideal for me. If you elect to go with Keith I would spend the time to make sure the motor is setup how you want to use it. With all that being said I think one of Keith's motors is a great option. It turned out I had a good bit of sorting to do with mine and while it runs awesome I just don't spend all my time at high rpm

I don't think that's workable. That's an earlier car. I actually thought it was the titanium one in your gallery. Good luck with whatever you choose to do.

BTW is that one of those CHP 427s using a production block?

I really don't think the Jegs / Summit Racing option feels right. Its kind of like Rev Tec vs S&S motors for harleys. To save 2500 - 4,000 for a crate 427 SBF vs roush, keith craft, southern automotive, danbury, etc, summit and jegs likely get some assemblies from china. I have no basis to make that claim, it just feels suspicious to me to have that large a differential.

The price difference can be attributed to what is not included.

You wont go wrong with Keith.

For street driving and I would say auto-cross too, I like a flat torque curve over the rpm range. Nothing more frustrating than mashing the throttle at 2000 rpm and getting a slow dog, at 3000 rpm getting pleasant power, and at 4000 rpm getting a tire shredding monster that you cannot control. Peaky engines can come on so sudden that they are difficult to drive. That said a few people like it and have no problems.

The other factor is what rpm do you cruise at the most? Well maybe what is the lowest rpm that you cruise at, would be a better question. You want the engine to be smoothed out before that rpm. It is a bit frustrating to have your engine wanting to buck and hop, when you are trying to cruise.

That said a choppy cam is music to my ears, but I want it to smooth out by 1800 rpm at the latest.

Hope one more opinion helps.

A place where so many want to be a in a car that totally makes them happy especially when mashing the throttle and expecting instant response. A lot of enthusiasts have to rely on friends or technicians to get these results. Others have the expertise to build cars and the drivetrains to get the results they seek making the hobby that much more gratifying.

I guess I should add that building ones own hot rod and having it perform to their expectation leaves one with a gratification that is hard to put to words.

Either way a hobby is a way for all of us to escape to place that that's good for the soul and proven that you just might live a little longer for it. I for one know that when my day comes I will have a smile on face.

Probably guys like me that grew up on two stroke dirtbikes and RZ 350 streetbikes...flat until they get up on the pipe, then practically unmanageable. Big fun when I was a kid...but I am 50 now. Give me a broad torque band for the street.

When you call, ask for Tony or Lance.

Lance owns the place now, Keith is not involved anymore. From what Tony told me, it's now called "Craft Performance Engines".

I spoke to tony today. He said hecan build the 445 stroker- actually its a 452 stroker now. But he said the criticisms I'm hearing regarding the high rev low end missing torque on the 427 has everything to do with the intake. The victor junior single plain intake will create that effect of a monster coming out above the 4,000 rpm range. He ssid if I elect the air gap edelbrock dual plane intake, i will get 570hp but a much crisper throttle and torque reaction from 2,000 rpm up.

Go with that 452 and don't look back! I am by NO means an engine builder but the different people I have consulted with all point to the Victor Jr. as being a good match for the 427 cubic inch motors.......I too was trying to find someone to tell me to use one of the dual plane RPM air gap manifolds and I was told it would suffer on the top end. I guess the only real way to know is follow the lead of your builder or actually dyno the motor and then do the intake swap and run it again. If I was confident switching to the dual plane would only knocked 15Hp off my motor and shift my power curve down 2000rpm's earlier I would have tried it. In my specific case I think throwing a dual plane on would have made it worse.....I think my camshaft profile 252I / 262Ex at 112 LSA installed at 112 ICL would have been at odds with a dual plane intake selection. I still would go with more cubic inches when its the same price. Good luck and keep us posted

That assplains why emails to Keith or his wife bounce back. Good to know.

No loss there... His product was/is good... but the man, didn't care much for him.

I guess Keith finally got what he wanted.......OUT.
