I am wanting to upgrade my 305 TBI engine. I am looking to replace the heads, intake manifold, cam, and rockers. I am wanting opinions on which type and what would give the most power from this swap.

 

do a search.... there are plenty of post on this subject

 

World products S/R Torquer heads, Edelbrock Performer RPM, TBI adapter plate, Holley 670 CFM TB and a higher lift ,mild duration,of course the amont of duration is up to you if youwant a lopey idle, LT1 cam is an affordable piece.

 

I have been looking for the Holley 670 cfm throttle body and all I can find are for a 4.3L and a 5.7L. Will these work or do they have one for a 5.0 and I am just not looking in the right place?
