The first thing that you do is sell the 750 and buy an 850 alcohol carb and forget about converting it!

If you still _want_ to convert it, you really need an understanding of alcohol and its fluid dynamics in order to convert your 750. The short answer is that methanol is consumed at a volume rate of approximately 6x the volume of gasoline. Therefore, your internal passages need to be 6x larger to flow the volume, but it isn't as easy as that.

I don't think that a few words on a forum can even reasonably point you in the right direction. Rather, years of experience in reworking carburetors offers any hope at all, IMO.

my under standing is that you need 2.2 times more methanol than gasoline, to give an air fuel ratio of about 6 to 1. if carb had 100 jets we would then drill 120 thou holes in the power plate just above the jets. then fit larger squirters and high flow needle and seats and a very good fuel pump with high flow filters....then you just get air bleeds looked at..

Re: how do you convert your holley to methanol

Long story short.....buy a methanol carb. The whole carb needs to be redone, not just the jets. You need roughly twice the volume of Methanol than petrol (not 6 times)

Your whole fuel system - tank, line, pump - also needs to be alcohol tolerant.

Re: how do you convert your holley to methanol

i ran a 650 dp on my 340 engine, it had 99 front and rears, we then drilled the rear out to 120 . make sure u run petrol back thru the engine if ur going not drive it that often, the methoal will rust the bores very fast.
