what compression?, race car or street car? hydraulic or solid? i think with that large of a motor it would be smart to run a different intake then the L76

Street mainly, the L92/L76 is just what TSP quoted me.

Just playing around with the idea, I know it will be a few fews/months before any numbers are put out by any members/shops.

so around 11.1-11.5 compression?

maybe like 242-248 114+2 that would drive nice, but that is just a suggestion, would have a nice wide torque curve

heres what you guys arent realizing, two factors intake is limiting rpm peak to around 6100-6200 on smaller cubed motors let alone a 454, and valvetrain weight with those heavy valves and a hydraulic cam, this motor is going to want to go much higher then 6500 and after that it will float mostly. so why spec such a large camshaft?? why kill all the low and midrange power , but you cant take advantage of the top end power of that big 257-266 cam, because of the intake and valvetrain. but thats just my educated opinion.

one of those problems is solvable in the sense if you want to go ***** out, get a sheetmetal intake made, or wait for the itb intakes to come around. theres at least one company making on now and another company designing it.

as for the valves, im not a guru, but perhaps so sort of modded ls7 valves could work, arent they made out of titanium or something similar in wieght?

yeah that is a solution, but he said he is running the L76. and i know ls7 valves fit on the seat of a L92 head, because i put them in a l92 head before for test fitment, they are just .100" longer, which that problem could be solved a number of ways. and yes the ls7 intake valve is titanium.

And the stock intake LS7 intake valves are garbage for a high performance usage. So you wouldn't be ahead of the curve at all there. You would be better off buying bare LS7 heads and putting aftermarket valves in it.

I've given thought to that set up as well.... a LS7 top end (but worked over)
