what you guys recomend I use on my 89 coupe

im runing a 86 block with flat top pistons with a 1.7 RR i was goin to add a cam but was afraid their was not goin to be enough clearance

it also has gt 40 upper and lower, 30# injectors , bbk shorties,70mm throttle body, 75MM MAF,pullies, 373 gears, and a ZEX 125 dry shot.

wantd to know whats a good plug to run and whats a good gap for this combo in order to get the maximun out of this bolt ons
im hopeing to have it all tuned in for the track this weekend and hope to run some where in the 12's

thanks

I use auto lite 24's gapped at about .054 if I remeber the gap correctly. Never had any problems with them Theya re like $1 a plug from Walmart thats where I find the best deal.

hey what about autolite 764 thats what I have on my 99gt wth the blower is their a big diffrence between the 764 and 24

i think 764's are for newer mustangs. autolite 25's are stock for 5.0's, i range cooler is 24

Get 24's gapped at .034. Earlier I didnt see your 125 shot sorry.

ya .034 is a little small for Nitrous...id gap em around .40 thats usually a good number on the nitrous cars i have seen.
