Re: using SBC for methanol? Can i do it?
The .030" over 350 in my Vega has been on Methanol for 15 years. It's an easy, simple combination.
ANCIENT 1st design AFR 210cc 23 degree standard port aluminum heads that have been angle milled to 55cc chambers. No porting, just a bowl blend and cleanup. Vic Jr., HP950 alcohol carb, about 14-1 compression with Manley pistons and low-drag oil rings, a Lunati 50140 roller with 1.6 arms on the intake and 1.5 on the exhaust, K-Motion 1.550 springs, stock GM steel crank, Venolia aluminum rods, 1 3/4" headers. Crank trigger ignition locked at 40 degrees timing.
I use a Powerglide with an 8" converter that stalls 5900-6100 depending on weather, 4.88 gears, and 14.5x32x15W Hoosier slicks.
It is relatively cheap and easy to build and maintain. It runs 9.30's @ 143.50-144 in a 2300lb. (with me in it) car. Launches at 6000, and goes through the traps at 7500. Shift at 7200.
I use a Mallory Comp 250 methanol electric pump, big port Holley methanol regulator, -8 lines from the fuel cell to the carb, and -10 return line from the regulator back to the tank (very important IMO).
DO NOT use aluminum fuel line. The methanol is very corrosive to aluminum.
Every few years, depending how much I race it, I dingleball-hone it, throw in fresh rings, touch up the valve job, new valve springs, new aluminum rods, new cheapie Lunati roller lifters, bearings, and I'm good to go for a few more years.
