Hey guys, friends with Chase Romano.. Ne ways
He got me on LS1TECH, Im building a 358 SB Carb 750 Demon, Bought long tubes.. (2210) and wondering about ground clearance..Also wondering about the computer inside... I wanna yank it out and use all mechanical gauges and use autometer in the cab to read.. Think this is a good idea??

I would stick with the electrical gauges so that you dont have a bunch of bulky mechanical lines everywhere.

You can rip the computer out and run electrical gauges from autometer.

2210 long tubes have great ground clearance, it's the y-pipe or whatever you do from the headers back that you have to worry about.

What heads are those and any reason in particular for running split ratio rockers?

Looks like a pretty nice combo, but please switch the rockers around. The 1.6 rockers should be on the intake and 1.5 on the exhauts. In David Vizards SBC book, they dyno tested 1.5/1.5, 1.6/1.5, 1.5/1.6, and 1.6/1.6. The all-around best combo was 1.6 intake and 1.5 exhaust. I assure you this is correct regardless of what your buddies tell you. Lift and valve acceleration on the exhaust side just isn't that critical.

Quoted for truth. I also offer the example of the better LS1-based camshafts. There seems to be a trend of more aggressive lobes on the intake which accelerate the valves faster and increase lift. It may not show up at .050" specs, but if you look at .100" duration numbers you'll see that the intake has a more aggressive profile. This is the case with the Futral cams and many of the Thunder Racing, LSx camshafts. I know your engine is a SBC and not based on Gen III technology, but advancements in valvetrain technology and knowledge can be universally applied across the board.

I'm with Mike. Swap the higher ratio rockers to the intake side.
