Its not LSA that makes or breaks computer compatibility, it is duration and overlap. The stock 305 peanut cams are 109* LSA.

That's not a mild cam ... u better have a good tuner or get the ebl n learn to tune , bigger injectors , higher fuel pressure , more initial timing , ... the whole tune will need to b redone spark advance Ve tables etc.

Except he has a MAF TPI setup and would have to swap to speed density to run the EBL.
