I have a 434" sbc with brodix track 1's.Its 15:1 comp and I need help with a camshaft.This motor has been run with two cams.Nitrous cam--lobe seperation is 112,intake is .705 lift and 273 at .050.The exhaust is .659 lift and 282 at .050 and 4/7 swap.Other cam was .705 lift and 281 at .050 on intake and .648 and 291 at .050 on exhaust.ground on a 108.How much power will be lost running with nitrous cam with out bottle.The nitrous cam is in the motor now but I hardly use the bottle.Would I be better off with the second cam on a 108 ls.I run a victor jr and a barry grant 1000cfm carb with product engineering fuel system.Heads flow 292 at .700 lift on intake.Thanks.Great site by the way.

434 Elco,

Do a search on the username "John Wilson". John has a 12.5:1 - 422 SBC with Dart Pro 1 heads that has run 10.05 @ ~132 MPH weighing 3550 lbs. The Camshaft Innovation cam he is currently running is definitely different than the norm, but the proof is in the puddin'!

John ran a "typical" cam previously and so far has picked up quite a bit for a cam swap. I have A CI cam as well and am itching to try it out.

Your Vic. Jr and 4150 carb is on the small side for your combo. There is some power there as well.
