Need help fast please

[mytight95]

Ok i have a buddy and we have finished putting his mtor together, and completely got everythign ready to run......rockers adjusted etc.....we had a set of plugs in it......but after setting timing etc......it keeps fouling them out........we believe it is not the carb because he has a barry grant carb preset for his application........doesn't smell rich........but isn't firing properly.......

we put bosch plugs in and we are sure they aren't right, however edelbrock isn't open today for info and i cannot find anything on their site.......so if anyone has any ideas please reply soon.......


we want to take it down the road for the first time, but we wated to get the right plugs this time so that he doesn't waste any more money.......


he has edelbrock victor jr heads
Barry grant carb
victor jr intake
347 10.5:1 comp.
etc etc etc.....


thanks

They take autolite 3925's but run 1 step colder 3924's I run also good if you have high compression like me.If he is running N20 run 3924 or 3923's.
