LA roller cam ideas

[Pound]

I have an '89 ram with a tb fuel injected 318. My question is: is there an aftermarket towing/rv cam out there for this that retains the roller lifters? If not can i advance the existing cam to maybe improve performance. Emissions are NOT a concern where i live. I really hate to reuse a stock smog cam, but will if i have to. Thanks for any insight from all the experts out there!

THIS! ^^^^ Oregon, will fix you nice... Put a good true double roller timing chain on it, new matching valve springs help.

Does the regrind require new pushrods?

Does the regrind require new pushrods?

Possibly, at least you knew to ask. You can buy a Comp adjustable pushrod, for about 20-25 bucks. Mock it up, see what length you need.

Another question: does the stock computer play well with mods?

You added a new twist, with the factory EFI... Emissions doesn't matter,when working with stock 80's EFI systems, they are self limited without ECM mods. I like grind 1254, it has a wide lobe center,(117), moderate bump in duration @ .050 and lift. Not gonna get a big h.p. gain with a EFI cam swap, you need to pick all the small detail up on early EFI.

Comp Cams offers cams for this sortof build.

If your running a electric fuel pump:
the short snout 254HR-12 PN# 20-628-9

If your running a Mech fuel pump:
the long snout 254HR-12 PN# 20-618-9

I just installed a Long snout 262HR-12 PN# 20-612-9 in a roller 360 for my 86 Ramcharger 4x4 and it was a night and day difference between the mild 318 I had in it before.
