I know, a 600 will work well, but this car is going in the hands of a 17 year old. I think the 450 will run well enough for him to get into MORE...
Did some researching of the numbers of my various holley throttle bodies. Seems my 390 is in actuality a List-4548 450cfm. I think this will be...
Yes, I agree. I would rather err on the side of rich than lean. However, the maximum CFM rating of the carburetor does not dictate a rich or lean...
Ratio411 You are spot on with my thinking also. We are talking about a 17 yeaar old boy here. He is driving the car now. Currently it has a 250...
While those are all good recommendations (I noticed yours too shadow). I am going to use something I already have, which is enough holley parts to...
I did some calculations using this formula to determince CFM requirements for the engine: CFM= [(Cubic inches x RPM)/3456)]x Volumetric...
Not to be argumentative but how can an engine run fine on a two barrel and have such problems running a small 4 barrell? I see no reason that raw...
Anyone using the "Tri Y" headers? They look pretty compact. Anyone know how well they fit the Mave/Comet chasis? brad
Nope, no screw in studs on this budget built. I went with the 268H as I had a choice of 5 cams in the kit I am using. My machinist and I agreed...
Thanks guys, those recommendations seem to be in line with my way of thinking. I'll let ya know how this engine works out once its in and running....

Whats the best way to check for that? I saw in one thread where someone has a similar exerience and it was the starter that was draining the battery.
My sons '73 Mav with 250, Automatic, keeps killing the battery. YES it has a stereo system with I think, a 1000W amp. However, its been in there...
New Distributer, same deal! I'm back to thinking now that maybe it's fuel related. I just don't see how. I have a clear fuel filter between the...
The problem with checking for spark when it quits is that it will fire right back up, first attempt, every time. If it would just quit for good I...
back to the drawing board! So far i have removed the gas tank, it was VERY clean, blew out the fuel and vent lines, replaced the rubber lines,...
No Dice....I spoke too soon!!! The Mav petered out on my son when he was on his way home this evening. It would restart then die when he'd try to...
Ok, for good or ill I put a new ignition module (DSII) on the car last Friday. No problems since (knock on wood). If the problem resurfaces I'll...
Thanks guys. I may put a coil on it and see how it goes. Lots of good ideas. Again, thanks. Brad
