Any predictions for rwhp????

Alright, my short block is at the machinist getting balanced. I would like to get as close to 300rwhp as possible with the new setup without spraying or boosting while still retaining TPI. With the Keith Black hypereutectic pistons I bought, the engine will have roughly 10.1:1 compression with 64cc heads. Anyway I will list the specs below. Since I haven't bought the heads or cam yet they are subject to change if better solutions are listed.

87+ roller block bored .030"
Keith Black hyper pistons
GM PM Rods
Clevite77 bearings and ARP bolts throughout (I'm not sure if these matter much)
AFR 180 or 190 Aluminum Heads
1.52 Aluminum Roller Rockers
ZZ9/LT4 Cam
TPIS Big Mouth
AS&M Runners
Ported Plenum
24/lbs injectors
TPIS 52mm Throttle Body w/Air Foil
!Air System
2600 Stall Converter
Custom Burnt Chip

Other Mods I'm doing at the same time:
SLP 1-3/4" Coated Headers
CATCO Direct Fit Cat
Flowmaster 3" Cat-Back
Aluminum Driveshaft
Spohn SFC's
Spohn LCA's
Spohn Panhard Bar
New Bushing All Around

I'm sure I'm missing other things but you get the general idea. As I stated above, I'm hoping this mods will net 300rwhp. I work with a guy that has a Honda CRX running 13.1 N/A with full interior. I couldn't imagine doing all these mods over the winter to find his car is faster than my V8 The car is not a daily driver but more of a weekend cruiser.

Thanks in advance for any suggestions.

300 RWHP? Probably not. Not with a TPI setup anyway. you'll probably be making a butt load of torque but hp I don't think so. Just my thoughts at least. Most I have seen out of a TPI setup is 400 RWHP on a built 406 SBC.

yup thats the weakest link, sounds like you have/or will be getting a nice setup, but the TPI is definatly holding you back..maybe a HSR or one of the other intakes like that...why put all your money into the motor, then sufficate it with a TPI intake???just my $.02
