I ordered some Stage 2.5 PRC 5.3 heads for my truck today, from TSP(Matt).

I'll let ya'll know what kinds of #s it puts down and then try to get some vids of it on the dyno.

I last put 318 down on a mustang dyno and I'm hoping to get somehwere around 375ish or so on the truck intake.

 

sounds great what is the chamber size? and what compression will you be shooting for...

Matt@TSP has to ask the machinist in the morning if he can do it on these heads, but i want them milled to 54cc and that would put me at 10.96:1-SCR and 8.65:1-DCR, Matt wasn't sure how much they could be milled. Hopefully 54 wont be a prob, i don't think it should be.

 

had to go with 57cc and still needed custom pushrods, but that will put me right above 10.5:1

 

Sounds good, I'm interested to see how well the heads effect your numbers.

 

me too!

 

How much did they mill the heads and what pushrod length are you going to use?

 

milled .045 and 7.350 pushrods

 

so are you going to dyno this with the heads being the only change from the last dyno?
what cam are you currently running...
Dave

 

yeah, just to see what kind of difference it makes.

a custom ground cam 224/224, .563/.563 on a 109.6(110)
