Heads w/ TREX v2.
Heads w/ TREX v2. Hey guys i got a killer deal on some ETP 245s with 55cc chambers. What do you think of this combo on 347 with a trex cam? Right now its in a car with stock 241s. Approx how much power do you think i'll make over the 241s? The other question is are the heads too big for 347 ci motor ????? Thanks alot
if your going to write senseless comments on my threads 
Getting back on topic.... Is there anyway around flycutting ??? Im not sure if i wana do that myself and i dont feel like pulling the motor apart to get them done professionally. Because if thats the case i will just have that done to my forged pistons (thinking about spray down the road). The car has arp rod bolts so i feel confident spinning this motor up there. As far as high compression, we will be running 112 octane

I would be nervous on stock rods (if that's what you have) but I know some have done it.
I honestly do like high rpm screamers but the bottom end and valvetrain gets expensive real quick.

1st thing ETP 245 will NOT Work with 347ci you need at least 408ci.
2nd 55cc damn the Valves will hit the Crankshaft not just the Pistons
lol
If you dont mind the question by killer deal is it less than $2000 or more??

Guys Im building his forged Short Block wich will be 15 to 1 comp with these heads. the heads should do well the 245s dont flow anything crazy and cam a little larger then a t-rex is what it will need

To fly cut, you pull the heads. There is a tool, that goes on a drill and you insert it into a valve guide hole on another set of heads and put them on the car to cut the vavles. If you are building an engine, just order the right pistons.
You will have to cut quite a bit with 59CC heads & a T-rex. Might not even be safe for the piston, I'm not sure.
I noticed you are going to run a forged shortblock. Probably need -14cc valve relief pistons. Check with whoever is building your engine.
15:1 compression? Race gas only engine. How are you going to accomplish that compression and have valve reliefs for that H/C set up?
Yes it will be done with out a problem i have built a few around here so its not the first.
What I was saying was, I would not run a stock shortblock to 7300rpm. Would probably go boom at some point. Did not know you were getting a forged engine.
