Ok, so it's time to get the Fairlane ready for the bracket season here. Last season I put a new camshaft in to try to get more out of my engine. The car slowed down quite a bit. The car died on the line, which is in the carb tune, which I'll be working on, but once it got going I lost MPH- it was going 110 at the stripe before, and 95 after. So, when I put up a post here, the general concenssus was the converter was mis-matched, and I needed a stall speed of ~4000-4500.

Well, I want to bracket race this year, but I can't afford a good converter. So, i'm stuck with the 10" one I have in there. Although I probably know better, is there anything I can do with the tune of the engine or the timing of the camshaft to make the situation better? The cam in there now is a Comp Cam, 242/246 @.050, .544/.522, 106 LCA, solid lifters, installed straight up. The converter is a Hughes 3000-series converter, C4 tranny. See my sig. for more about the motor. I need the torque peak lower in the RPM range. Help please!

I think my biggest problem (my shortcomings) is that when my partner and I first built the engine, we were inexpierenced and thought that by throwing a bunch of expensive go-fast stuff on the motor would make us fast. Those two were dumb kids, thats for sure. Now we're trying to make up for our ignorance by fixing the mis-matched stuff i.e. bigger cam to take advantage of the flow of the Vic. Jr. heads, holley carb instead of the carter, locked distributor, and now the converter. Maybe we should just pull out this motor and start over with a stock 302 out of a 'stang I have- it could turn out to be cheaper. We just want to run 12's consistently (or anything consistently), without the headaches, and above all else, finally start racing! Anybody else ever have these problems? Sorry to complain...

Two things.
1) Lock the timing in at 35 degrees.
2) Loosen the valve lash about .010
(I love solid lifters )

Do you really think that starting over with a new engine will be cheaper than a new converter?

Well, yeah. I don't mean start over as in all the machine work and everything. I'm swapping a running 302 coming out of a '70 Mach (a 351C is going into that) that I can have. It is a stock motor except for a performer intake. I could put that right in and use the headers, carb, distributor, and converter that are in the car right now. Might be a little more simple to dial in for a novice racer like me.

Alex, is that .010 on intake and exhaust?
