Hydraulic Roller Lifters w/LA Block?

Time to stick the stock-style lifters and cam in there and not dick with it; it's not worth the price of admission; the $1000 plus labor you just spent on a retrofit, you could have 3 nice magnum roller blocks. First rodeo? When you mod, you get bit sometimes.

Thanks for the perspective Poison.

I'd be the first to tell you I have no idea what I'm doing and am just trying to learn as much as possible as I go. I suppose I can always go back to the drawing board in terms of cam but are you saying this is a known issue to you veterans or something?

I originally built this motor for drag racing over 15 years ago and it always had hydraulic flat tappets until now. This time 'round my goal is a motor for daily street driving and overall reliability in L.A. traffic. The shop that did my heads recommended this particular cam to compliment their work so that's what I went with...

I have run roller lifters in an LA block without issue. This is a 76-77 era 360 block and you will immediately see the difference in the casting around the lifters. I would say someone got handy with a grinder in your block. The roller cam in my block was from Competition Cams and was ground on a LA blank. The roller lifters are from Hughes.

Ha, yeah that's what I said. The shop swears they didn't touch the lifter bores/castings though and that they just smoothed out of the oil galley some and that the issue is with the original casting and that 70's Mopars are just notorious for having crappy/inconsistent castings.

I had deep chamfers in my 340. I have MRL Performance lifters and no issues at all. Hughes also has some that will work.

Thanks dude, I'll let them know to give those a try!
