JJ you out there? What ya think.

Barney, there are cars here in Div 1 that I know dont have anything other than off the shelf catalog parts and are that fast..although I will admit that its way easier with injection and alcohol...with alky injection you can kill it to basically an idle off the stop and that lowers the amount you have to run in the stop...

Two other examples...although my roadster is light for sst (2450)...I have a "junk" 496..small roller, 12.5 comp. 305 cc heads, PG, 4.56's, 16/33's...I raced in a local SST series this past year, I have a bunch of time slips 10.90 at 149/150, and it only went a best of 8.70...

Another guy who posts here had a Nova a few years back, 511, Canfield heads from Bill Mitchell, alky hat, 2800 lbs...10.90 at 149 all day..8.80's all out...

So I'm thinking a "regular" 540 can do it on alky easy...with nothing more than off the shelf standard stuff...

I really believe the key is less time on the stop...you see Gary is running 4-5 sec's, you gotta get it back to about 2.2-2.6 secs...
