Great intake and heads. The general cam specs sound like the Chevelle will have an extra 100 CID and you will have an extra 1000 RPM, use them all and it'll be a race, if the Chevelle doesn't go up in smoke at the line. Who are you considering grinding the cam? Chuck

Haven't got that far yet. But sure have some new fire under my butt to get the patchwork completed and start putting it all back together. If you have any recommendations they are all greatly appreciated. Mark

MArk call Comp Cams they will custom grind one for about them same cost as an off the shelf cam. When I called they needed my motor, tranny, and rear end info as well as what I wanted do do with it. Then matched it with all the needed components. Now the roller lifters were a little pricey but.............at this point does it matter

Solid or hydraulic roller? If you keep the lift just under .600 you could use a solid flat tappet, not fight hydraulic roller lifter pump up, have more useable RPM, and save a considerable amount of money to spend somewhere else on the car. With power brakes vacuum is an issue (as is modulator vacuum) to consider. But is easier to live with a higher idle speed with the four speed. For a SFT something like 232/240 @.050, .570/.590 110 LSA for the gusto or 112 LSA for more manifold vacuum. peak power should occur about 6750 RPM. Shift at 7000 and hold on. Chuck
