I'm starting a 2.0 build and I have set of idf 40's but I don't know if they'll keep up. It's going to have the biggest cylinders and pistons I can buy in it with a knife edged and balanced crank, port and polished heads, big cam... Blah blah blah. I have a set of IDF 40s and I am wondering if they will be able to keep up. Any help would be appreciated.

Is this a 4-cyl engine? Are you using dual 40s?
For reference, on a warmed over 2.0 that we did many moons ago, we found that we could not get the choke size that we wanted with the 40s. A better choice would have been 44s choked down just bigger than what was available with the 40s. I think the limit on choke size with the 40's was 32 when we ran with a 4-cyl car. The last season we ran it, we had the stock 28 chokes bored out to 34 and had the machinist attempt to taper the choke similar to what they were. (they are a parabolic shape) The car ran the best the last season. Then we decided to go to a 3.2 and be done with it. |
