Well throwing a PSI # at you is not the best to help really. Being it'll depend what you are using as FI. You stated you want a blowzilla (2.1L roots blower) are you sure that's not going to be over kill?
Are you planning on doing rods pistons etc ?
Really with wedge motors they can't take as much comp or a psi (compared to same sized/speced inline) Just the nature of the beast. Not at all to say they are weak or bad.
For knowing when you pass what 92 is safe start looking at other builds what the get away with, tuning is key for sure. But there are also limits what the metals can take. Remember gas we get isn't always perfect so don't tune to the finest hair for .01 extra HP unless it's a bracket car.
I've built a ton of motors planned even more for people and tuned a bit. The only 5L I did was retrofitted to carb touch of boring, and a big lumpy cam.
A 5L plus a t-56 would be a joy stock with a good roots on it yum!
Please feel free to ask any questions or tell me I went over your head. I tend to do that lol.

Thank you for the link.
I already have the blower and will most likely use an aftermarket EMU and 45 lb injectors.
I also have a low miles 1988 5.0 that comes from the factory with forged pistons. They tend to split this block in half when they get into the 800+ hp range, but seem to live a long and happy life in the 550 hp range.
I have Desktop Dyno and have had great luck using it for N/A engines. The problem I have is it doesn't have my Twinscrew blower and I haven't had anyluck getting the same results that books and magazines have posted, so I don't feel comfortable using it for this engine. Another thing that I really need to know is when I've gone over the 92 octane limit.
They did this build a few years ago, the problem is they don't say if he used the 58cc or 61cc heads and they don't tell what octane fuel he was running.
How well does the new Kenne Bell BLOWZILLA/FLOWZILLA work? Muscle Mustangs and Fast Fords Editor Richard Holdener recently tested the Kenne Bell BLOWZILLA/FLOWZILLA kit on his own engine with the Westech engine dyno. The little 302 had #185 AFR heads, Comp Cams #274 cam, 75mm throttle body, 77mm mass air, Kenne Bell Switch Chip and 42 lb injectors. The combination made an amazing 508HP at 9.2 psi and 484 at 7.5 psi with a pavement ripping flat torque curve (453-483 ft lbs). 483 ft lbs @ 4000 rpm. That's 500" engine torque numbers. The boost never varied or dropped off from 2500 up - and there was another 9 psi left in the supercharger.
My goal is to have an engine that makes 500-525 hp and around 500 tq.
With the price of gas likely to go up, I want to use as much ignition timing and compression as practical and still get this hp at full throttle.
As you know, the timing of the cam events can make a huge difference in effective compression, fuel requirements and fuel economy.
The higher my static compression, the better my fuel economy when I'm not on the gas. Since I want to drive this car, I want to get around 20 mpg on the freeway and with the 6 speed I should only be turning 1400-1500 rpm at 70 mph.
Everything hinges on telling when I have gone over the 92 octane limit. I also have the option of using water injection that will let me increase the boost by 2 or 3 lbs as well.
Thanks
Ken
