its as tony says ,
had i known two weeks ago i would have bought it back as the need for one came up ..ended up spending nearly 600 for a racetronix kit
its a reds with his 340 based XP pumps
they are a drop in , tight but they go
low low miles
was in a full weight a/c GN w/ stage 2 that only saw C16 so no alcohol or water corrosion issues common with pump gas
wasnt a daily drive but saw some street use as it was driven to the track and only made a couple track appearances .went high 9s 140 but had the adj oil pump bypass fall out on a pass ,no oil pressure is not good. car went back to stock
i run a twin in my 86 (with 93 alky) and still on stock fuel lines, the twin 340s should be capable of supporting to 900+hp with proper fuel lines
heres the flow chart for the twin reds
