302 to 347

[Dark Horse]

I'm new to this site and I wanted to start a thread for my new project. Original combo
302 shortblock 92 hypereutectic
TFS R heads
TFS stage 1 cam
Vortech Mondo intake GT40 base
75mm T/B
76mm mass air
42lb injectors
Paxton Novi 1000 on 5psi.
Hooker Super Comp L/T to 3" X with
Aero flow mufflers

Changing to
347 Stock block .030 over
Scat crank n rods with Probe pistons #10666
TFS R heads
TFS stage 3 cam
TFS R intake
90mm T/B
Lightning mass air
Same Exhaust

The best I did with the boosted combo was 459hp and 388tq on a water break dyno. I'm tired of boost and want to go N/A I've already sold the charger and purchased the stroker kit. I have everything to complete my project just no time. I hope to have a comparrison soon to see if I really can have the same power minus the boost.

I don't think you can make that kind of power with an n/a 347. Should be able to get to 400ish though

I think youll be more like 350-400

Combo should be right around 10.5 to 1 with 205 heads I hope it makes more than 350-400hp. I've had the block square decked .010 and the mains line honed the pistons come out about .005 I found a fellow stanger in my area who is running a similar combo and made 474hp and 415tq sounds crazy but he's friends with Jeremy from UPR who made more power on smaller cubes. My only issue is I have to port the living hell out of the TFS R intake runners almost match a Fel-pro 1262, I unfortunately have to run the 1262R so I've got a lot of work ahead of me.
