hey all i'm tring to figure out why my slant is stalling out after the rebuild.

at times she will start up and idle okay take her up to 2500 rpm okay above that flat falls all her face?
other times she'll start choke fully closed then just die after a min?

heres my set up:
eldelbrock 500
clifford intake
hooker header/open right now
.0075 off head/stock gasket pocket ported.
clifford .449 lift cam/inner/outer springs
used orange box ecu/lean burn delete
89 oct gas with booster added

any one know what psi a stock mach fuel pump flows?

Paul

it was because i came off the stock mach. fuel pump and bumped up the line from 5/16-3/8 to carb it was causing fuel pressure problems.
went back down to stock size to carb NO more problems.
