Guestimate on 383 #'s Hello all. Ive been looking to buy a FD RX7 with an LS1 coversion done. I found one fairly local to me that already has the swap done with what looks to be a decent stroker setup. Here's the basics of the engine:
HSC Built 383ci LSX V8
4" Eagle crank
Eagle rods
Ross Pistons (11:1 CR)
Race bearings
AFR 225 heads with spring upgrade
DRE Rev Kit - Hydraulic roller
Comp Cams Custom Grind
ARP Head studs
Cometic Gaskets
LS6 Intake
Ported GM Throttle Body
ASP Underdrive Crank pulley
It also has full length headers and a 3.5" single exhaust all the way out.
They have rwhp estimates at 475, but due to the shitty tires on it (225/50/16 crap radials) it was spinning on the dyno.
Going of that basic list above, does their estimate sound about right? Also, I do not have the cam specs as they aren't listed. I can also imagine that a FAST 90/90 setup would be a lot more suitable than the LS6 intake as well.
Thanks

Tell someone to strap it on the dyno correctly, no reason it should be spinning on the dyno IMO.
Can make a guess on power either, thats just as important as motor size.

Thanks for the replys though.
