building a engine that will run e85 found a roller cam and lifters at a good price ,question is its in the 750 lift range ,ive never had a roller and the lift is way higher than ive been using is this a to big or just right cam
I agree. In fact, ill go as far as the cam should be one of your last decisions in a build. Typically bottom end is given with what you have. Or willing to spend/work with. Head selection is typically based on bottom end specs. (Obviously you can't go with tight closed chamber heads if you have big dome pistons above deck line) Head configuration with fuel/air manifold selection will dictate best cam performance options. Building a motor around a cam selection? Very much limits options.Well, It all depends on all of the variables. The first one is: will your heads, valve spring pockets, and pistons
be O.K. with that big of a cam. The second is: Automatic or 4 Speed? 3: Power Brakes or manual? 4: How are
you getting the E-85 into the engine? Sometimes a deal isn't a deal! I would call the cam manufacturer and ask
if this cam is a good choice for your setup.

Back in the day, I switched from a 635/645 - 276/[email protected] mushroom solid(similar to Mini Express) to a Comp [email protected] roller in a 451/400 12.0 CR with valve pockets & OK piston to valve clearance ported 906's, tunnel ram w/ 2-650 DP's. The roller was over a tenth & 1 1/2 MPH slower. Comp re-ground the roller to 660/280 which was equal to the mushroom in performance.
Get advice from the manufacturer (it helps to talk to real tech guy, not just the phone salesman).
...gonna be a tight fit???........Gooder??????????
Key is to get the experienced Mopar cam tech to pick a good lobe design for your combo.cutting down the cam to a livable lift is a good idea I would have never thought of it first time thinking of using a roller the price is very good for the cam and lifters that's why I was thinking of it thanks
