Hey gang:

I am building an engine and before I button everything up I thought I would make sure others have had good
success with this same combo. I am a little concerned that I might need a modified eprom
thanks again for your replies.

If I were you, I would pick a more ECM friendly camshaft. Try to keep the LSA at a minimum of 112. Unless you really want to jump into DIY prom, and tune away, because, that combination will definatley need tuning. Only more complicated with the 110 LSA. Those cylinder heads are not a good choice for a TPI engine, IMO. Maybe try a Brodix, or AFR, TrickFlow, etc. The MAF will be more forgiving than a S/D system. Might need a converter that stalls @2800, but with your gears, you might get away with the 2400. BTW, did you mean "large tube runners"?

 

Great engine, mismatched induction. That's a great HSR, MiniRam or SuperRam motor. LTR's are going to choke it very very badly.
