Would be nice with headers but I have to stay with the manifolds...
I can't find any good (and cheap) roller cam. Will do some phone calls tomorrow and see what it costs to have it re grounded here.
Here’s the thing, a roller cam isn’t cheap, period. There in the area between $300 & $350.
Here is why you STOP penny pinching and start thinking!
Swapping to a FLT Hyd. cam looses you power (vs the same spec roller cam) and will cost close to the same as a roller cam by the time you purchase a cam, lifters and pushrods to replace what you already have.
Spend once on a roller cam and that’s it! Done! IF you need roller lifters, they are cheaper than Hyd. flat tappet lifters.
