am fitting twin 40's to my c20xe, standard spec apart from head skim and enlarged exhaust ports a.t.m. want engine running before i go any further with tuning. what jets should i be running? dont expect to get the jets in and car running perfect without r.r. setup but just want it to fire up and drive for now then plan on changing cams, pistons, valve seats etc and then r.r. setup when funds allow. also what fuel pump is best to use and will i need an f.p.r. to get correct fuel pressure to run? haven't done much with car carbs so starting from scratch really. i know they're jetted for a 1.6 8v atm so will prob be a mile away.
