Anyone care to guess at the horsepower this one will put out?
My newest build is a 445ci Windsor stroker based on a Dart Sportsman block with a 4.155" bore and a 4.100" stroke. Scat forged crank, scat H-beam rods, and Probe pistons. Keith Craft is doing the block work for me.
The heads are TFS CNC Twisted Wedge R heads, which have been drop shipped to Joe Craine for massaging and flow testing. Out of the box, these heads are supposed to flow 330cfm @ .600", so I'm very confident they will work well on this application. They are 225cc heads with 2.08" intake valves and 1.60" exhaust valves. The cam is a Comp custom hydraulic roller, with a 294/298 advertised duration, 166/169 duration at .200", and 244/248 duration at .050". Lift is .615"/.621". The intake is an Edelbrock Super Victor intake. Compression will be 10.7:1, with an 8.15:1 DCR. The cam may be a little lacking for this size engine, but it's going in a heavier car than a Cobra and I want it to have plenty of low/mid range grunt. I'm shooting for 600hp/600lb-ft.... |
I will guess:
580 HP 570 TQ |
550Hp and 535 TQ
I'm staying to the low side on my guess. In any case, it sound like you will have one great engine. |
No more than two opinions? Ah, c'mon guys.....
|
well James yales 427 small bock was 610hp soyou could go 640 easy if the engine flows like his did...WB3
|
Hey WB,
Any links to his build? |
My old 408 was at 615 but with a much bigger cam than you have chosen. I would guess your at the 550+ range.
Don't need no big block. |
What cam and heads were you running?
|
The cam was a special grind
Bullet 670 lift and 266-274 I-X @.050 solid roller Made all it's power up high 6,600 but would not run on pump gas. The heads were out of the box AFR 205's I have since detuned and now am around 500HP |
It's a small block, couldn't possibly break 300 horse max.
:LOL: |
well gee wizz if were only 300 at max that musta made those big blocks we bsmacked at runngun less than 250hp:rolleyes: :p :3DSMILE:

Blykins I dont know if James Yale had a build site for his Daytona or not but that engine your doing is going to be very stout ,I know james found a 100 hp just using the BB 4into 1 headrs instead of the quad pipes the Daytonas have it was all tested ther on Crafts Dynos.sounds like fun WB3

The only thing I'm unsure about is the camshaft. I want to have a great deal of good manners on the street, but I don't want an RV either.
It's hard to find examples of setups like this one on the web...so I have nothing to compare against. Probably the closest comparison I have is this one : http://www.clubcobra.com/forums/small-block-talk/82248-world-460-all-aluminum-windsor.html Now granted, it's 15ci larger than mine, but I think I may have the edge with my cylinder heads. This 460W also has a pretty stout cam....254/260 @ .050. That's kinda what makes me think I'm not choosing a large enough camshaft. Thoughts? |
i think about 595hp and tq 585:rolleyes:
