OK my application is one of a DAILY DRIVER and TRACK car. AMP used a GWATNEY PERFORMANCE LT NFC cam. The graph below is THAT cam on my car comparing a side by side comparison of the LT NFC with an LT2 LT5TB and a MSD NW103TB. A side note here that this LME 416 has forged pistons with valve reliefs already in them so I could easily run the TRACK ATTACK or SS4 Cam but we felt those cams were a little BIG for the daily driver side ESPECIALLY since I did NOT want to use a higher stall speed convertor.

Obviously the engine wanted MORE air because it is a LME 416 with VERY good heads on it. This is fully evident by the fact that car made 25 more HP than the LT2 combo was producing. GWATNEY"s own testing showed that the MSD manifold DOES NOT pick up any additional power on a stock cubic inch engine compared to an LT2 LT5 combo. The LT2 combo picks p a very solid 15-20HP over a stock LT1 manifold though.

My RPM range when tracking is the 4500 RPM range and UP. I run an A10 so the car in track mode is pretty much always in that range and above. I AM running 14:1 compression and E85.

The car with this COMBO gets around 14 MPG on the highway pulling an 800 pound loaded tire trailer at around 80-85 MPH. When driving on the street the car gets 12-13MPG typically. Those numbers are indicative of a VERY efficient engine based on the power it produces along with the fact it is on E85 which burns at a 30% faster rate than 93.

The ONE thing we ARE going to change is that AMP will be tuning the A10 tranny because the car DOES have some minor surging issues when at idle. It is not bad at all but the tranny needs to lock up at a slightly HIGHER RPM level than what the stock convertor is allowing. I DID NOT want to use a higher stall speed convertor because those inherently have SOME amount of slippage in them and that is NOT really ideal for a road racing application.
