Marc, how much does a complete 4200 engine weigh in comparison to a complete 250, any idea!

About 150 to 180# less.

Yeah, that's a 4200's oil filler cap! \:D

Seriously though, yes it appears under all that is a 4200.

WOW, after the vid of the Brazillian drag car with the twin turboed pushrod Chevy (250??) this one should really haul.

Interestingly, it looks as if they have converted to the LS type ignition coils. I remember reading something (I think EFI-DIY) posted about doing that, but I don't recall the why of it(at the moment).

Amazing effort regardless.

The head MS guy did some COP ignition coil measurements and the LS2 coils that this guy used are "just crushers" 170mJ spark energy - just for comparison check the MSD LS performance coil spec.. I wish I could find the video link..


Got it...
