rocker arm question

i have a set of roller tip rockers for a SBC and i want to put them in my 4.3 V6 before i put it in. are the rockers the same?
and they say even the roller tips can free up some horsepower, is this true?
thanks guys

:cool: yes its true while not as good as the full roller rockers they go a long way to making life a little easier for mr. valve train!


check with you're local speed shop to see if they will fit!

haha thats awesome. i got the set of the roller tips for free which makes this literally free horsepower haha

i would shake you like a baby if you didn't tell me how you got them for free.

hahahahahaha. a buddy of mine has got a 70 chevelle with a 383 and he ran them for about a week (which is maybe 20 hours for him) and then took them out for some full roller rockers. and when i told him i was building a 350 he said he had them and hed bring them to me. when i asked him how much he said forget and gave em to me.

good score.... i wish my friends didn't all drive jap crap or else maybe i'd score parts from them as well

same here, i know ZERO people besides a handful of friends i know in my town and the rest are hotrod meets in the summer that come from all over the state.

Some of the 4.3L engines are going to require self-aligning rocker tips similar to those required by the Vortec engines. The self-aligning rockers will have two thin washers on either side of the roller to keep it from sliding off the top of the valve. Your stock rockers will have a slight indentation in the tip to keep it on the valve stem if it is a self aligning rocker arm. On the older, non-self-aligning type engines, the holes the pushrods come through in the head are sort of rectangular and hold the pushrod straight up and down which maintains the alignment of the rocker.

this engine is early 90s. when i took the stock rocker arm off to test fit one of the roller tips the rocker arm didnt move around too much and the pushrod had very little movement. everything looked good so ill see what happens. ive also been told some 4.3s had roller cams. anyone know how to spot a roller cam v6 without taking it apart?
and as far as free stuff man let me tell you lol. i went to my uncles to get a set of heads he eas giving me and i walked away with the heads, almost brand new pistons and rods a new water pump and an almost new oil pan.
and an old school pro stock hood scoop :)

i just checked and my motor doesnt require self aligning rockers. thanks for the heads up man!
