Roller cam

Im having thoughts of maybe sticking a hdy roller in a 74 351W block, I have a 89 302 that cam factory with a hdy roller cam, is it possible to use a roller set-up out of the 302 in a 351W?

i doubt it would work. i think the cam would be a little to "small" if its a stock spec. cam to feed your 351.

the 302 has bosses in the lifter valley that bolt the spring retainer for the lifters down. the 351 does not. you could use a aftermarket roller lifter with individual bars but remember the firing order is different for the newer motor

could you drill and tap the lifter valley in the 351W to accept the retainer? Im sure id have to modify it considering the 351W is wider, but would it possibly work? and I wouldnt use the factory 302 cam, there are alot of grinds out there for the 302 w/ hdy roller..and a windsor (I think) would benifit greatly from a hdy roller

it is possible but for the time involved a set of lifters from crane or comp will slip right in

I have looked at the hdy roller lifters from crane and comp...even doug herbert...they are all more expensive than solid roller lifters, I want the driveabilty of a hyd roller cam, and I cant afford the conversion lifters right now, it be easier and less expensive to go solid roller whitch I dont want to do right now..Im sure someone has done this before...but Id like to know what exactly I have to do to make it work..and thanks for the replies, I really need some help on this one...

you might be better off to put a 302 with a carb in your car. the windsor will make good power but not on a budget. then you could jut swap the cam to eaqul the hp of the 351,and it will bolt right in

well, this is a 12.5:1 351 with (ported) world product heads 2.05X1.60 valves, victor jr intake, and a 750hp series holley, so Im kinda committed to it...I have a "big" solid flat tappet cam in it now but Id like to go the hdy roller route because of durability issues...

oh didnt relize that. what kind of duribility issues? ive had up to a 590/600 260@ 50 solid in cars ive built and aside from all the adjustments ive had min. problems.

well, I use alot of spring pressure on flat tappet cam's to take advantage of the grind at high RPM, and its really hard on the solid lifters, (they dont last long)..
