Will I be running too lean?

glad to see you'll be converting!! you absoultly will happy that you did!

great link. was looking for something like that. though i wouldn't say it's a myth per say, however, while it's not tuned for the best operation, it still will be able to run the car with out killing something unless you go crazy like Dave did! not saying i disagree with you, but i feel there is much more flexibility in the MAF system over a MAP.

hehehe....


Yah, keep the duration lower than mine.. 293 advertised is a bit much.

True, but I think its more due to OBDII than just a MAF. OBDII has more flexibility in trying to keep the engine running right vs. OBDI. Reliability / economy / emissions were major concerns with OBDII while performance was more of an afterthought.

19Cutlass94: good deal. Even with the stock motor if you can tune you can usually pick up power. No two motors are the same from the factory, so even custom tuning a stock motor can be beneficial. If you get the pin-outs you may be able to just swap the engine harness and not the interior harness like us L bodies can. You just gotta swap some wires around for the tach signal and such.

95Grandam - If I were you I'd just put on the large port 3100 or 3400 intakes and run with that. Make sure to keep using the original 3100 FPR and injectors still though. Those small ports are costing you at least 10hp if not more. The 3500 heads flow more but you'll be getting pretty far from the parameters of the stock 3100/computer so likely that won't gain you a whole lot for the cost. And a cam will screw things up too much up. Go with large port manifolds and then a 3500 upper if you wish and you should get some increases but anymore than that I think it will be not worth it until you can tune. You're wanting to do the same thing as the this thread is talking about. Since you can't tune (94/95) you're in the same boat.
