Ok Guys here you go! A little late but late better than never!
4" Eagle Crank, 6" Eagle Rods, L-19 Bolts, JE Flat Tops .030 over Cleveland Block which is 408" , A3 SVO Motorsport 50cc Heads Flowing intake 357 @ .700 and exhaust 234 @ .700 all at 28 inches, 274/[email protected]50" .745/.722 lift on 106 solid roller, 13.25:1 compression, A331 Motorsport unported intake, 750 Barry Grant Methanol Carb. 1.76 Powerglide, 5800 stall, 4.86 9 inch with 14x32 Hoosiers, 2500LBS Pinto. 1/8 mile only!
I did manage to put a little heat in the heads today for the first time. I have the Moroso restrictors in the block and took the drivers valve cover off to check oilling due to restriction and it only had splatter on the valve cover, however this may be due to the studgirdle keeping splash down? Otherwise it sounds good and can't wait. Just to let you know I went with the glide to try and not run wheelie bars and keep the front end down off the line. I have a fresh C4 with PA brake and the works waiting if it does not perform. After I establish a base line I am going to send the intake to U812 which is a member of the board and see what kind of results we can get from his porting.
Hope to get it to the track this weekend!
Any advise or suggestions? How about a guess as to what kind of time slip the 408 will produce?
P.S. I think I will be changing my login from Pinto 306 To Pinto 408!!!!!!

Not sure, but it seems like the 750 carb might not be big enough. Are you running methanol or gas?
Sounds like it should be a very quick ride!!

It's not going up that hurts. It's going down that hurts.

hehe...yep! Coming down hurts. Going up, its like whooooaaaaa.....woo hooo....uh oh this is gonna hurt (insert expletives)...BAM there goes the pan & headers, among other things.

Heres a good example...guy tore up a lot of parts. BTW he was footbraking it...514" with 400 shot I believe. normally runs 6.30's in the 1/8 but on the juice I've seen it go 5.60's. Notice all 4 wheels are off the ground. But he took home $500!

Maybe off topic a bit but whats up with the 1/8th mile? Is that a southern thing ? I know when we lived in South Carolina when I was a kid my dad raced 1/8th mile sometimes but I live in the Northwest now and I don't think Ive ever seen an 1/8th mile track or not at least in the last 30 years.. Are they trying to keep the speed down or whats the deal with 1/8th mile tracks?

I don't know. In NC most old 1/4 mile tracks have been changed to 1/8 mile because the cars were getting faster over the years and there was not enough stopping room so instead of lengthning the track for stopping room they elected to shorten it to 1/8 mile. There are a few local tracks who can still run either 1/8 or 1/4 mile. Most street cars run the 1/4 but most faster bracket cars only run 1/8 because over the last 20 years everyone has changed the rear gear to only run 1/8.
Hope this helps.

1/8 mile is easier on the car, the driver, track officials...everything about it is a little easier. Cleaning up an oil down on a 1/4 mile track from a faster car is a pain if you don't have 30 people helping....and down here in the south getting help cleaning up when the weather's 110 degrees and 70% humidity is like pulling hen's teeth. Ain't gonna happen. 1/8 mile is also more challenging as far as bracket racing goes. VERY little room for error if you're top end racing, at least compared to running 1000' or 1/4 mile. Downside to 1/8 mile....not as much MPH and it seems like it's (the run) over really fast.

OK, First night out
5.98 best time, 114 Best MPH, 1.31 Best 60' in the 1/8 mile.

EGT seems a little high at 1311, may need a larger carb. 750 Barry Grant running now.

add yes you need more fuel 1200-1250 egt or reduce timing a couple of degrees , that will reduce egt temp also
I'd try the fuel first, do you run any water in the block or heads? you need to see a temp rise of 15-20 degrees during pass also

Hello 306, Did you do the roll cage and rear and front suspension builds yourself? Or is it from a chassi m
manufacturer, or did a local shop install it for you? Thanks

P.S. Your car really looks great! Ken
