Help with 392 stroker combination

93NOTCHLX · 12-08-2001, 07:53 PM

I have finally decided which direction to go on my pony. Instead of a blown small block combo, I am going with a stroker 392/393. 500hp and TKOII with 3.55s will make me happy. I plan, for now, on the FRPP 392 shortblock with AFR 185 heads. I still kepping coast highperf in mind though. I'm not settled on a cam yet (looking for suggestions and experiences).
My question is this:
I would like to use a truck lower with a downs upper and a 70mm TB will this hurt torque on a na combo? Or is the torque loss of a short runner intake acceptable due to the extra inherent torque of a 351W stroker. It will still be a while until I undertake the engine as I'm doing the platform items first (upgraded rear-end, suspention, brakes, roll cage etc).

i don't think your going to get too many answers in here as we tend to deal mainly with only 281 CI.

(extra small blocks) may want to try the Windsor forum they can give excellent advise

I just had a 408C stroker built. It Dynoed at 537hp @6300 rpm. I'm running a cam with 244@.50 and 6.23 lift. 108 lobe separation. It's got 11-1 compression. I running a Torker intake and 800 cfm double pumper. The torgue of a stroker is fantastic. This is a street motor in a 70 Mach 1 show car. If this was a race car we could have gotten over 600 hp maybe even 650. RAY
