Ok, I'm building an evil 357ci Windsor for a customer. He wants 600hp on pump gas and then he's planning on a 200hp shot of juice on top of that. This won't be a daily driver, but will see some definate late night weekend runs(gimme two and the go....
). I'm looking for opinions on camming and head volume. This is the most radical combo I've been commissioned to put together and I want to make sure I'm going in the right direction. Obviously, it's going to have a solid roller, figured on 11-11.5:1 comp. Cylinder head wise, I'm looking at TFS Highports, AFR 205's, Vic. jr's, and the new Dart Pro that was in last month's Race Pages. Intake will be a Super Victor, not sure if we are going carbed or injected yet. Tranny will be a baby C6(I know, a glide would be better) and it's going in a typical 3000-3200lbs. 90 Mustang. Let me know what you all think. Thanks!

Don't bother using a stock block, it wont handle it, first off. Its possible with pump gas, if you consider jet fuel pump gas. However, you could do it with a turbo, thats the only way I think that could be attained, and using pump gas. From there, I don't know what components, besides a 4340 crank and premium ARP bolts and the like. Good luck man, you have one hellava project.

Hi, actually, we are using a sonic checked and beefed '71 block and nitrided stock crank. Why would you need forged to support only this much? I figure the shift point to be around 7000-7300rpm given the lack of compression to really make the cam work. I know 600hp on pump gas won't be easy, but it should definately be attainable. I see it this way--------> Engine Masters Challenge contestants were doing it a hyd. roller under 6500rpm with the same cubes and pump gas, a solid roller and more rpm on a similar base set-up should get me close(?).

Don't laugh too hard. I don't have the recepie, but our car club treasurer has a small block Nova with a 408 and Brodix heads and intake. Puts 91 octane from Skinnies or the Quik Stop in the tank (tank - not cell), drives to the strip and runs 6.90's~7.0's (1/
without laughing gas, 6.15's wheels-in-the-air with a ??? shot. (Carries his pit scooter in the trunk - that's too cool) Motor makes 600+ on the dyno w/o the NOS. Don't know who did the work, but it's spot on. For comparison, other friend has a 66 Falcon drag-only car with a 514, FRPP CJ heads, Victor intake, 'glide - runs 6.70's typical.

I would be Extremely leery of using a stock crank and block. I am putting together a 331 for a customer who will be using a supercharger and I wouldn't use less than a sportsman block but would really prefer a Dart and we're only looking to make about 500-550hp. I know a local player here using the cheapie 347 kit and the rods are going out of round and the cast steel crank isn't doing great after a string on 6.80 passes on n2o. Oil pressure in the dumps. I would look toward at least the afr 205 heads, super victor intake, 830 or 950hp series carb and plan on turning a lot or rpm to pull 600 horses. You'll also need lightweight pistons with a good ring pack like .043, 1/16, 3/16 low tension or 3mm oil ring std tension. It's not the kind of deal you can just throw the parts together and out comes 600hp.

CKELLY.......That nova probibaly has a 4.125 bore. check it out again.


...................................

With fords 4" bore their is no way in hell a NA 357 is going to make 600hp on pump gas at 7000. like I said...pixie dust


Now use a 4.100 + bore and spin it to 9000 now we're talking nascar.
