Another update.. The car was loosing oil pressure at WOT on some test hits. Oil pressure gradually got worse so I pulled the motor. I got everything stripped down last night and found out I put mains #1 and 2 on backwards.. Sooo new crank bearings once again..
I also got my final turbo placement worked out. These things will be getting a good shot of cold air now! I still need to fab up some intake tubes though.

Love that movie! Truth is those are some very thick TIG welds. Being the terrible fabricator that I am, The welder was forced to fill some rather large gaps. I made the cuts and tacked everything in place but relied on a friend (oil field guy) to complete the welds. I didn't want to take the chance of them cracking as I don't plan on bracing the turbos.

Update. The 370 is FINALLY back together.. I stayed up for 30hrs straight putting it back together with the mad scientist. Turns out some junk got caught up in between the Pistons and wrist pins so we had to open them up to .002 but other than that no major change besides some fresh bearings. Track times should be coming very soon.

Nice! Sounds like me-I can only get a lot of work done when the babies are sleeping- so I end up working fro, 10p to 6a with no power or air tools .
I may have missed it, but whats your rear gear ratio?

It all depends on the execution. If you cut a jagged hole and jam a pipe through it, then heck no. But some nicely tapered screamer pipes with a slick trim ring around it wont look to bad at all! Plus they sound mean haha
