Thanks guys! When I ran at Maxton I didn't have a roll bar so they limited me to 135 and said over 140 I'd get the boot so I ran 135-136 nascar style all weekend, just going around and getting back in staging. I'm currently running a '74 Pontiac 400 with '68 #16 heads. It's kind of a mystery longblock engine from a Judge clone car I was parting out that burned. I don't know anything about the cam, rods, pistons, valves, headwork, etc. I just cleaned it up, painted it, and used a Canton RR pan, melling pump, Flowkooler, MSD, Edelbrock, BG carb and so on. I don't run it over 5200 RPM because I don't know if it still has stock rods in it.
I plan on finding/building a serious engine ( IA II or similar) and using a Keisler 5 speed setup with the .82 overdrive. I built a 2.41 rear with Moser tapered bearing axles, Ford style housing ends etc.for it since I last went to Maxton so I want to test it out. It worked fine at Sebring but the straights aren't as long as Maxton AND I have to slam on the brakes to make the next turn. So reaching ultimate top speed isn't really possible there. With the power I have now I figure about 150-155 is probably the limit at Maxton. Hopefully I'll find out this weekend!
