im running a set of STOCK edelbrock rpm peformers on a pontiac 354.
rockers are a stamped roller tip crane 1.52:1
i have a set of PRW's 1.65:1 full roller rockers.
do the pushrod holes need opening up?
before you ask "what the hell did you put those on a 354 for"?
i bought the engine for a grand. couldnt pass it up!
this engine is going into my 30 oldsmobile.
replacing a junkyard 389 and a stock th350
with this aluminumheaded 354+ (dont know the bore until i pull the heads)
and a st-10!
have a great day!
