Have the datamaster scans if anyone would like to see. Did get a pull of 362 but lost and couldnt print.......this motor should have over 400rwhp. Any ideas? Thanks.

Well, for starters, some better pictures would be nice.. I couldn't read anything at all in the second one. Also, it looks like at 5000 rpm, the engine was only making about 160 hp and 170 pd/ft of torque, did I see this right? Also, a detailed list of mods would better help us. Let us know some more info and hopefully we can help you start really making the power.

 

Whats your full list of mods?

 

For some reason they dont know how to use the dynapack either with a dyno chart like that.

is your tranny in good shape? could it be slipping?


did you hear any kind of miss

 

did golen install the cam, or did you? Could be degreed wrong, or could be an ignition related problem.

 

Just looks like the guys can't use the dynapack. Shame too.

Should be dont know how to diagnose that one.......one thing I notice is at 85 mph or so on the interstate it starts to get a vibration but dont know if it is tranny related or not.

 

Golen installed the cam......the motor came as a complete longblock(I sent them my heads, intake, etc).....

 

Dont know about that as I have no clue.........but the guy does seem pretty knowledgable on it and I have seen him use it before. We dynoed several cars this day to include my gto.

I heard with an auto you have to lock the converter to get a true power estimate.

Does the motor use any oil? Did you degree the cam in the block? Timing chain set up dot-to-dot?
