the 20psi was on the dyno only, the max boost it saw on the street it was about 15-16 psi, still kinda high on pump gas i guess, plus you never know what you really get at the pump. i will make some changes for the next one.
yes, there was some signs of detonation, i was expecting head-head gasket issues before doing this.

Just read everything! Kick *** build man with some kick *** numbers. But know one has asked the one question I want to know. How much did that Beck intake cost you? I currently have the Fast 102mm and TB. I don't have everything together yet. Some has told me not to use the Fast with my build. Not sure about it. I called Fast and they told me that it would hold up and they would stand behind that intake to do what I want it to do. But I really love that Beck intake you have. Also What MM is it?

Damn shame on the detonation. Sorry to hear that. I don't run above 14PSI on pump gas. I do 110 at the track when I'm running running full out with no issues so far.
What's your compression ratio and what timing did you run at your max boost levels? All those things will affect how far you can take that motor to before you see detonation. I'm at 8.7:1 CR. I max boost at 23PSI to get my 908RWHP.
On your block decision I'd say no matter what block you get if you get serious detonation it's going to let go. But since you need a new block I'd go with something that gives you more bolts per cylinder to give you better clamping force and eliminate any worries there. Also if you really want to run on pump gas then I'd choose a pretty low compression ratio also.

i kinda wanted to lower my cubes to help my turbo being more efficient, since crank and rods were in excellent condition im just going to use the same rotating assembly, lsx block at 4.030 bore sounds pretty strong to me, im giong with diff heads as well.
believe me, no more pump gas for me!!! i had enough

Sounds like you needed a better tune and some meth when running the pump gas. If you are going with a different type of block. I would suggest you talk to Sean @ ERL. Research there work on here. You will not find anyone that has bought there blocks saying anything bad about them or I didn't. ERL will be doing the LS6 long block 427 super deck l for me. They will be doing the top end also. Working my AFR 225 heads to accommodate a 1/2 bolt for max strength. Being I don't want to deal with trying to sale them in order to have 6 bolt heads. The cost seems to be pretty reasonable. Sean will work with you anyway he can. He will not try and act like he knows everything. If he don't know something right off he will find out and let you know. That is my 2 cents. They are other respectable engine builders on here as well. You really just will have to search them out and see what one sounds better and will fit your means the best.
