What is the intake centerline on Richard's profile?

 

its 110

 

TTT one more time anybody else

 

With such a low LSA, I've heard you may run into some problems with the vacuum accessories like the brake booster. Maybe chime in over where the F-Body guys hang out. I'm sure there are a few of them running a 110 LSA over there.

 

You said that exhaust duration was added for the dope. You're willing to sacrificing your na performance for the dope? Why? Tweak your setup. Let's look at this.

You want the engine to be as efficient as possible. Lets say the perfect camshaft for your na setup is a 224/222 grind.... But, you use nitrous frequently while racing... Do you change the whole camshaft? No, you open up the exhaust. How so? Cut-outs. Flip of a switch and your setup is now maximized once again for whenever you need it.

Have Richard design you a na camshaft.

 

Might consider a reverse split cam. Im not shure but I thought you wanted a higher lsa for nitrous and FI applications.
notices the lsa Id go with something like this

99-227/224-114
or the reverse but on a higher lsa
99-230/224-111

just a thought but honestly Id send my flow numbers to a reputable custom grinder he should ask alot of questions like stall size, gearing what your plans are where you want power how much the vehicle weighs, n20-FI etc...

Bigtex is knowledgable on those motors in trucks I would be pming him and doing alot more reading you need more knowledge before decision time. Peoples opinions are fine but in the end its your money and you get to drive it.
