Titanium 58 Ford...... |

I did some figuring, and it takes 700 flywheel horses for a car that weighs 3,800# (thats with driver) to achieve 10.20's. That means the heads have to flow 340 CFM @ 28 inches to support that kind of power. Jim Kuntz needs to talk to your dad. For a 3,200# total to do it takes 600 horses, and that will require 290 cfm @ 28 inches. This is what a regular poster runs with his Fairmont. For another example, the Hemi heads, fully race modified, and with 5/16th's stem valves flowed 365 cfm, better than my Hi-Riser 427 heads by a significant amount. Most ported C-J heads are in the 275 range. The 240 rod is 6.795" long which is doable, but I have seen them break. I believe it is not as short a stroke as you do, since the journal size must be reduced .315 to get to 2.123 diameter (I believe thats what the truck 240 journals were, from memory) throw size. |
