Hi guys!
I recently installed the new 400cui Pontiac engine and the TH350 i built this winter, in my 64 Bonneville. To be honest, I was disappointed. It fires right up and it runs nicely, but it just ain´t fun. It doesn´t even really smoke the tires at a wot launch... Maybe you guy´s have a clue what´s wrong, considering the parts I installed/efforts I made:
69' Pontiac 400 Block
69' #46 Heads (72cc) with 2.11'' intake and 1.96'' exhaust valves milled in, ported
wiseco pistons
Crank and Rods Pontiac, balanced
Edelbrock Performer intake
Edelbrock Performer carb 1406 600cfm
Howards cam 410021 dur @.050 214/224 Lift .444/.467
Rhoads variable-duration lifters
Comp Cams double roller timing set
Pontiac HEI distributor
Hooker Super Competition headers
Dual exhaust
I run the engine on 100 octane
I don´t know what gears I have, but at 60mph the engine revs a little over 2000 rpm in third with stock tires.
