-350 bored .030" over with 3.75" stroke crankshaft
-Stock TPI intake
-Edelbrock Performer Heads
-Cam 0.495 I/0.502 E, 218 I/ 224 E
-1.5" primary, 2.5" collector Y-pipe to 3" hooker catback
-1.5 roller rocker
-10:1 compression

more info in sig

i had to guess abit on the cam and some other numbers, you didnt give the lsa.

Knock of 15-20% and it should be accurate to your net flywheel numbers

My go at it came up with 359hp@4900 and hellacious low-range torque that tapered off quickly at about 4000 RPM (probably due to the TPI).

lol.. I would have posted the graph too, but I dyno'd it on another computer that's not hooked up to the net. That's almost exactly how mine looked except I used the Chevy 383 instead of modifying the Chevy 350 like you did.

nsimmons

looks about right, it would probably dyno around 250rwp about the limit for a stock tpi

Could you guys dyno it with an LT1 intake, 58mm TB and an LSA of 110.

i am looking at my NAPA parts book. here's everything.

Dyno2000 - 62.99
DESKTOP DYNO SE - 62.99

that's what they'll cost you.

I used a 850cfm single plane manifold, pretty close to an lt1. I dont know the flow numbers on a 58mm throttle body, i'd guess close to 1000. you gained over 50hp and lost about as much torque at the low end,

I'd go for it.
