Hi everybody, building my first 496 and could use some input. Mostly street with some track.
Car is a 66 ss chevelle. Has a legend/Keisler 5 speed manual
S60 rear with 4.11 ratio
Weighs 3650 with sbc and 200Lbs driver
Block and machine work done
80s 454 block
Scat rotating assembly
Edelbrock rpm intake
Edelbrock 6045 oval ports
I initially liked the comp
Comp tech suggested
Any decent roller rockers that will fit under original valve covers?
Heads and intake have been gasket matched
Should I have them flowed? Do these heads respond well to porting? Or is it a waste of money on these heads?
I will need a carb or possibly fuel injection?
Recommend any books and videos on bbc assembly/building/tuning
Thanks in advance, not looking to build a race car or a tow truck. Hot street with some daily when I can.
Thanks, would steel rockers be more durable than aluminum? Better valve cover clearance? I was originally building
A 454. Does anyone have experience with these heads on a 496? Worried it will be super choked.
Scorpion Rockers has a model line that says claims smaller body and shorter polylock for increased clearance. You would think a steel rocker would require less metal for the same strength but I don't know if they are actually manufactured like that. I believe you can buy the Comp Cams and the Scorpion rockers in a single piece from the big mail order sites to test with.
