Stock valves on stock castings..... discuss.

 

Not bad at all for stock valves....they should make some good power......whats your combo gonna be?(cam ECT...), and who ported them if I might ask? good luck.........Joe

 

Why would you port them and leave the stock valves? You could pick up another chunk of flow by using larger valves. Nice numbers though.

 

The heads are LE "budget" heads. 561 castings with stock valves. I am doing a budget build up. I'm not going super cheap but I'm finding the best deals I can. The car is going to have 1.7 RRs on the stock cam. Car has long tubes and full exhaust. My whole plan for this car is to have no more than 6 grand into this car and that is including the cost of the car itself. I've got about 1400$ left in the budget. Car will run low 11s and look good at the same time.

 

Not w/o spray or a cam it's not

 

It's going to get sprayed.... rest assured at 3000 pounds and under 100hp of nitrous it will move! LOL

 

Good deal

 

I'm hoping for 340 at the wheels with the 1.7s. 430rwhp on the spray.

 

with a decent cam and a good tune with supporting mods you will easily make 340 rwhp
