I get confused when I hear people say that the 230 CC head is too big when if we would have gotten a set of 215's we would have had to have them ported to death to acheive the level of power needed to make a car that weight run 9.90's. I thought if you have too much head or too much cam, you won't have any torque or responce and in a race situation the car will leave soft or have a slow 60' time, this car has been 1.41 with suspention issues that we eventually worked out. Last year I met a guy with an all steel and original glass 65 LeMans with 10" tires running a 383 sbc with 245 CC Pro Topline heads going 9.50's @ 139-140 MPH, over the winter I was told he did some motor work and back-halved the car and he's now going 9.30's @ 145.
Yesterday, my uncle went to Cecil and got backed off the line twice for leaking transmission fluid, he checked seals, lines, gaskets and everywhere, couldn't find the leak, he got back to the shop, I jacked it up and fired the motor, the converter was split wide open! It's not a spragless converter but it has a mechanical diode (ratcheting sprag) The converter was not built for this exact combo but it did work well in the solid flat tappet combo I mentioned in my first post. We intended to have the converter set up for the Chevelle but now it's shot. Last season my uncle went to a test n tune session and ran a 10.23 then right back to a 10.47 so we called it a fluke although all the track increments (330' 1/8 mile E.T. and MPH and 1/4 MPH) were accurate, I can't recall what the 1/8 E.T. was but the MPH was 105. That's the only E.T. slip we can't find to analize. The car has been 1.41, was consistant mid 1.40's but now we can't get it back into the 1.40's. We are pretty sure that it is the converter though, I had a converter done by them (Transmission Specialties) back in 1995 when I was only running 11.20's, the sprag broke in half after less than 20 passes and Bob Maze basically told me Oh Well, you make too much torque, I sent it to ATI and have been running it since!
I will be pulling the converter out this week to have it cut open, I will keep you updated. Thanks D. Miles
