they should be #302 closed chamber heads with flat top pistons about 20 in the hole

the tbi roller cam engines respond well to a carb and duels

I droped a lunati voodoo roller cam into my 88 engine and just pulled it and stuck it in a 91 tbi 318 with the 4-v/headers

knocks back 19 mpg in my 85 truck with a 29? gear

comp 901-16 springs are a good upgrade that drops on with stock seals and you can loose the rotoators on the exhast valves for more lift

will be a performance gain for sure but its stil a 150 HP 318
