Stage and TA blocks bring their own problems...Sta ge One vs Stage Two, even fire, odd fire, uncommon oiling systems, parts availability, cost, etc. Unquestionably, they are stronger and were built for abuse and high rpm. The additional head bolts are really nice.My gut feeling is that the 3.8 block is a safer choice than the 4.1 once one is into the tens. This is based upon experience and not science. I think the 3.8 will make the same hp because it will accommodate a bit more boost time and again without splitting.Spending money on forged cranks, good rods, and lightweight pistons will allow one to approach 6000 rpm a lot of times without tossing something. Lightweight pistons usually have their own problems arising from the need to use more cylinderwall clearance due to the piston alloy growth with heat. This rounds off the rings fairly quickly so it may be better to use a heavier, low growth piston for a driver. Also makes it more important to keep it under six thousand, imo.I tend to think girdles are not worth the effort on a well built engine. I suspect many will disagree with me on this.It's my opinion that high quality machine work and a really good fuel system are the two most important things in achieving long life in a strong street engine. Steel caps are rally a good investment IF the machine shop understands they don't just bolt on, followed by an align bore/hone.18 degs of timing will make almost as much power as 24 degs of timing but will make an engine more linear in its approach to the detonation line.Building an engine with nine second rotating parts will make one that is much more fun to drive in the tens for a much longer time. As pointed out above, there are not that many cars that will run 10.5 and even fewer that will do it every week end.
Damm that engine turned into a $$$$ pit fast . Amazing how they grow.. Good Luck with it .. What are ya running a chip or a Fast system ?? Remember DON'T DETONATE it and it will live .
Dan, I am glad to see you are still with us....Happy New year!

Branching off on other cars though. Figure if I want to play around now is the time to do it Happy New Year to everyone

Im thinking your buick powered rx7 fits right in. Do you have other irons in the fire?
Spoke with Eric this evening. Gave him all the technical info and spoke about goals of the setup. Went over some numbers and talked about his ability of flow matching a set of injectors just a tad bigger than 80's. I'd really like to get some 83's. But with not really pushing the envelope of the build, 80's should suffice. Sorry Mike. I'm staying with the stock un modded ECM. Classic 5.7 for 93/alky and another chipped for 110.
Jason, the mid range is good on that cam, but, I think you will find with your combination that it will feel like you down shifted at 5000 rpm and 6000 will there in a split second. I think shifting at 5800 will drop the rpm to about 5000 on the next gear. Should be no problem with your components. It will not have slowed down at 5800 but it will pump the lifters about 6200 or so. Being that it will be up on the cam at 5000, there will be little loss shifting at 5800.Sent from my LG-H810 using Tapatalk
