more power for oliver 88

colonel1958 · Oct 1, 2015

someone at one of my pulls, suggested putting a 1650 cam in my oliver 88 for more power. Currentley dynode at 62 hp. Pull in classes 5,000 thru7,500. Running 15.5x38's, sometimes 18.4x34's. Some of my competitor's seem to have a little more grunt than I do. This is when a gentleman mentioned to me about the cam. He said years ago he did this and it benefitted him greatly. Any advice appreciated.

I think that you would be better off to send your cam and lifters out to be reground for a puller grind. It will help but don't expect miracles, that extra grunt might be coming from some extra cubes.

If you're gonna tear it down might as well go ahead and stroke and poke to get maximum return on your dollar.

What have you done to your engine so far? 1650/55 intake and carb? 3 7/8 pistons?

probably wouldnt be able to tell the difference with just a cam swap, go after cubic inches

If you are turning the higher RPM than original; you can likely get as much advantage by having someone that knows what they are doing; "degree in" your stock cam. That will set your valve timing to where the valves open and close in a more efficient manner for the engine speed. On my latest Moline; someone had put a reground cam in and did not degree it. I pulled it out; put in a stock cam based on imformation I got from other Moline pullers experience; It picked up 20# compression on cold crank per cylinder and "came alive". No; the engine is not stock but the same principal applies. Just as ignition timing must be advanced to run efficiently at higher speed; the same can apply to valve timing. Depends on how much over stock RPM you are turning. ( many places allow 20% )

That is exactly what I have done so far. As I stated earlier, A gentleman told me to try bigger cam next,[1650] he said this would help,it did for him. I believe some of my competitors are definitely running bigger cubes. They have to much throttle left to play with at the end. I was looking for just a little more grunt.
