Sorry Ive been busy with other projects... But Ive got a lot of cool stuff done lately. I bought a tig welder this summer and Ive kept it busy after work. Most recently I helped and directed my cousin building a turbo'ed yamaha apex snowmobile. stock 150 hp with a programer and 10 lbs of boost hp unknown but deffinate improvement now!
Back to your question, the right manifold does touch the frame under engine torqe but I reused old warn out motor mounts that NEED replacement. the crossover works for me if I will ever find a ford front axle to match my newer drivetrain. The exhaust will be outside the frame unless I build a new header manifold setup kinda dealy job... Im guessing by now youve probly got your rig done and driving and mines still sitting waiting on a large work list.
Good Luck, sorry for being a few monthes late but Im still around sometime
