Towards the end of the day it just got warm and the track slowed down. Starting running rich around 10.8ish and i think that killed my mph. First time at the track ever and finally got got launching off the twostep.

So three years its been and through all the problems and headaches she is/was finally done. The last sunday out with her I blew a head gasket so now its bak to the parts lists and months of winter work now ahead. So questions for my syty guys

How far can you push the stock manifolds?

I'm guessing the shotpeened rods would be weak point over 450whp?

Basically i'm trying to take my setup to the new level without incurring huge costs. If i could spend 1500-2k in a rebuild i'd like to see 500whp or its fine if my setup is pushing it already and for 1000k just put it back together.

wow, you doing that on a manual 5speed? amazing!!
the stock manifolds have been in the 10's i myselve ran 115mph in the 1/4 with bad 60 ft, without meth and on 15 psi on stock manifolds, and i don't think the manifolds are something that is holding us back to go faster.
right now i added more timing, more boost, alky and ordered a set of drag radials, and shooting for low 11's high 10's on stock manifolds

Yea as long as you have the manifold porter they will not be the weak point they have gone 10s no problem.
