Tried a 75 shot last night turns out i had too big of a jet on the fuel so my air/fuel was 10.9 backed the timing off 6 degrees just to be safe. Kept the tr6 plugs in it since the br7s didnt come in yet. Ran a 12.4 @110 1.83 60ft. Dropped. 5 sec over n/a and gained 5mph trap speed. Gonna get a 100 shot bext.time out and hopefully get the right jets in it

It's all in the tune. A healthy stock bottom ended LS will take a 300 shot no problem but you have to have all your ducks in a row for it to live. Learn how to read plugs. Damage can be done easily if something isn't right with any power adder. Non projected plug such as a BR7EF is a must for any power adder.

I sprayed a 200+ shot through my old car (H/C stock bottom LS1) for a few years and it still ran great when I sold it.
