just to clarify... you need to check your valvetrain geometery... and stop listening to salesmen

well i wasnt sure about it b/c of changing from stock to full roller, and i was standing there talking to the sales guy at the jegs store... they suppose to be somewhat knowledgable well guess i learned my lesson there.... so i need STOCK LENGTH RIGHT???? i dont want to have to tear this apart again anytime soon until heads/cam would have done it now but the $$$$ isnt there

the best way is like adder said and check valvetrain geometry. to do it properly you should use an adjustable push rod length checker. I start with cyl #1 at top dead center and start there and work my way around the firing order bringing each such cyl up to top dead center and with the checker and roller rocker in hand I set the valve train up marking the tips of the valve stems with marker to see the travel and placement of the rockers then I take it back apart and check the marks and lengthen or shorten the checker accordingly till geometry is just right. then I measure the rod and wha la you have the correct length needed. I use comp cams checker works every time

the beauty of having adjustable rocker arm studs

yeah I know 77 stang! I say do away with the pedestal mount cause then you have to mess with freakin' shims under the pedestals

hmm i didnt think just swapping 1.7 roller rockers was so complicated figured just take off old ones install new ones??? didnt have to worry about pushrod length, only reason i got longer ones was b/c of pos jegs guy. so im going to have to get a pushrod length checker and check the length for my pushrods just b/c of changing to roller rockers?

Hey. im new to the forum and i was wondering what you thought the best fuel injected intake is. this is the first ford ive owned n im not sure what the best stuff is for them. i was looking at the BBK SSI intake. tell me what you think. n on your problem i think it might be that the distributor isnt in place correctly

no, you need to just check your geometry before you do anything... if its off.. THEN you buy the checker, find the proper length, and buy the right pushrods

problem is, he assumed your car was completely stock...you could have shaved heads, shaved deck, etc... those are all factors in valvetrain geometry.. put the stockers in and check it..

Jon82387

adder my car really is completely stock.... im almost 100% sure there has been nothing done to it, and can you or anyone give me some info on the valvetrain geometry???? im completely clueless to this how do i figure out if its all correct?
