416, ported PRC LS3's, going to a carb setup, is it worth it to go solid roller?
I have a 416 I bought from a buddy of mine. I'm going to a carb setup instead of the EFI he had. It has a Callies crank and rods, Wiseco pistons. LS3 ported heads with stock rockers w/ upgraded trunion. The motor is 11.4:1 compression now.
I'm wanting to know if it would be worth it to go solid roller or stay hydraulic roller? I know I could spin it higher if need be with the solid but it would be cheaper to keep all the hydraulic stuff.
Plus, while the motor is on the ground in my garage I was thinking of upgrading to a set of PRC 265 small bore LS7's or some RHS ls7 heads. Would that be a better option with a solid roller setup? I was also looking into a Mast intake. To me, a Mast intake probably wouldn't gain much on a ported LS3 head compared to lets say their black label LS3 head but if I switched to and LS7 head, I would see more of again with that head and intake. Let me know what y'all guys think.

I can't answer if it's worth or not cuz I don't know. But I'm doing a carbd 416 ls3 and I'm keeping mine a hydraulic roller. You may wanna include what all your planning to do with the car as far as full blown race car, or cruiser, or street strip. I'd like to hear what others have to say about it.

A properly done hyd roller will go 7500 no problem.
You should be able to make 650-680 with the heads you have with the correct cam and a mast 4500 intake.
I am at a crossing point with mine the next step to make more power is a set of mast ls7 and a new intake. This stuff cost about $6500.
I would say stick with the heads you have proper cam and intake and let it eat.

By the way, the heads have PRC .650 lift springs

A properly designed solid will make more power throughout the rpm range. The solid will cost more but can shine in the right application. If you run the MAST intake you will not have a shortage of air. A limited travel hydraulic would probably be the best middle ground. I'm faced with the same decision for my 416 and I'm going FTI solid but with a FAST 102.

I think the biggest bang for your buck would be to go with the new super victor ls3 intake. It features a large plenum and long straight runners similiar to the Mast intake. Should work well with what you have now and allow you to use a carb. You can always sell off the topend later if you decide you gotta have the Mast setup.
