Saturday me Bonnie is been stuffed on the Studka Water Dyno at the speed shop down the street.. have a good idea where my hp is but this will tell me all also found a young guy who`* shop has a CNC` machine for auto ; cranks ,etc...have to sit down and pick his brain for a stroker billet crank

*cough* Throttle Body bore *cough*

what?

Ahem... Stainless adjustable runner dual intake...Ahem...

*Sputter* Only if i knew what that was... *Sputter*

You'll know soon. He'll be done with it by late January. Then we'll see if he'll sell it to you to replace that plastic upper.

I will never give it up... Late January aye.... such odd dates...

You could just turn your engine into a 4.3L turtle... Bore it out more and use the 4.3L crank or have a billet one made but that'* going to be a big price tag and probably not worth it unless you are trying to make 700HP out of the engine.
