Putting a different manifold on my 408 for the fuel injection. My heads were milled .010" when they were getting ported. Do I need to have the new intake milled to fit, or should things line up fine since it was only .010"?

Who has some experience with a toilet setup on methanol? ET gains over a carb? I've heard some guys are a few tenths quicker and deadly consistent. I think it'll be worth an extra months play money to pay the difference between an APD carb and the injection. My plan is having KillerRons set me...

Think I've posted about this before, but posting again. I'm sick of the inconsistency I experience with pump gas in my bracket car, so I want to dive into the world of methanol. I've asked lots of questions of the local guys who run it, and get a wide variety of answers. I feel like I can swap...

For the next race season I want to run methanol. Ethanol was what I really was pushing for, but there is zero availability for a reasonable price in my area. I'm already running 1/2" lines and a compatible pump. My carb of choice would be the pro systems engine friendly setup. The big issue is I...

Ran it out to 5500 and shut it off to pull plugs. 1,2,3 and 4 look like this. Plugs 6 and 8 look dark brown I can't pull 5 and 7 because the header tube runs too close to use a ratchet, and naturally the tube is hot. Have 82/92 jets in, should I go up one size in the primary and down in the...

I've mulled over the idea of fabbing an air intake that I'd run through the factory battery location and draw air from the front bumper area. I've seen some guys run the intakes with dryer-like hose. Has anyone had personal experience with the performance benefits to such a thing? When it's hot...

I've been seriously considering switching to e85 for race fuel (mix my own, not pump garbage). Has anyone had any luck good or bad with this? I see carb conversions are readily available for my 4150. I run a Holley black pump, 1/2" lines and pickup. My main problem is finding a distributor...
