Did you ever get to completely disassemble one? I have one of these gators and was just curious about the motor...

Yeah, it's a stock LT1 throttle body. Engine is a 355. The MAP reading was 92kpa and the sensor is in the intake. I forget what baro was... somewhere around 99-100, I imagine

Oh yeah, this is a fuel injected motor, also. Stock TB is 48mm and I was just wondering, roughly, how much power I'd pick up by going to a bigger one... if the TB is, in fact, the restriction!

Thanks guys... a lot of reading so far!

So, which one is it?

And won't an engine have just a little bit of vacuum, no matter how "free flowing" it is?

I'm talking about engine power.

Let's say baro was 100 kpa and the map reading was 92kpa at WOT. Just wondering how much horsepower is lost from the restriction.

Is there a calculation for this?

Turns out he pushed out a freeze plug.

I bet he NEVER comes back to this track! :mad: He did an awesome job of saving it! I thought it was gonna flip in picture #3. Still not sure how it went from having the ass end farther down the track than the front end, to hitting the wall with the passenger side?! :-k http://i80.photobucket.com/alb...

Very nice!!

Awesome!!

Loose converters show weird stuff on the dyno when trying to compare track times!

10PSI at idle? That's not horribly low, is it?

Used motor oil on all my stuff, but it didn't set around forever, either. Primed it and fired it right up.

I'm not sure if people on here have done it THAT way, but I have read talk about clamping the rod at the parting line, tightly, to deflect it some, the machine it like that.

Me too. I thought they were THE go to guys?!
