Seems a little slow...

With open chambers and domed pistons you can run alot more timing at launch but it has to retard in each gear like this
1st gear 42 degrees
2nd gear 36 degrees
3rd gear 28 degrees


If you want to test this to see if it works before you buy a retard box then lock the dist so it has no advance and start at 36then run it and keep upping the timing 3-4 degrees and run it down the track you should notice your 60ft times getting faster and your mph getting slower. So now start back at 36 and retard the timing 3-4 deg at a time and your 60 will suffer but mph will improve. If you try this and you get these results then you know to go and buy a retard box.


One other thing that cam needs 150-160 psi to be happy and you should only be at 125-135 with your combo. Unless you milled alot off your heads. So either up the compression or swap the cam. Either way it should pick up time but it will be alot more if you leave that cam and up the compression. Your converter should be right for the cam Have you done a compression test??

And you could use some more gear like a 4.33 or a 24in tire. Not the 4.88 just about 1/3 of that

Smaller carb 650 dp will work just make sure it has the 50cc acc pump kit

904 trans is good for 3-5 tenths


Put the victor jr back on and give it some more fuel too.

You should be running in the high 12s

But dont give up you will get figured out you current times are pretty respectable I know of quite a few 360 340 cars that are slower than yours

Good luck
