On a sidenote, what has led you to fit a Mitsubishi engine to a Camaro? Was it just based on your previous experience with that engine and willing to try it on another testbed or any other motivation? Well, maybe some info about the bolting pattern would be of interest to the off-road folks who often adapt some "unexpected" engine and transmission setups (which seems to be the case of a Mitsubishi engine backed by a GM transmission) to their rigs.
The main reason for the Mitsubishi engine in the Camaro is for traction when I street race and no prep race the car. The lightweight engine that will make around 1400 HP and help get the weight bias around 60% on the rear of the car will help it to get traction.

The other major reason is all my research has gone into this engine. My stratified charge pre-chamber has been designed around this engine.

The 71 Camaro also has pretty much one emission device and that is a PCV valve. So I can run it as lean as I want.

My goal is to put it in SEMA next year and remake a factory decal that was put on the 1991 Talon/Eclipse 7/70 warranty for a play on words. In mycase it will stand for 7 second 1/4 mile ET and 70mpg.

Hi pgfpro
Can you share more info on this?
Is it something similar to Honda’s cvcc?
Thanks

Mine is more like the "Passive MAHLE pre-chamber"
https://www.mahle-powertrain.com/med...assive-mji.pdf

I still use my PFI for fuel delivery. My pre-chamber is designed to collect fuel on the intake and compression stroke and uses my own designed spray guided piston to assist with this collection. The pre-chamber has a rich A/F ratio to promote flame speed by a torch flame kernel and reduce misfire. This allows for the main chamber to run at extreme lean conditions 30:0 plus while still having a low numeric BSFC number. My turbo plays a major part in the design by having high airflow numbers at light load to promote air/fuel to the pre-chamber and increase flame speed.

Are you willing to reach this weight bias while parked or accelerating? IIRC the Nissan 370Z has a 53-47 weight bias while parked, in order to get closer to a 50-50 bias on motion due to weight transfer while accelerating. Well, a 60% rear weight bias on a Camaro would be quite impressive. Are there other mods meant specifically to reach this goal?

This would be parked with me and everything in it.

The Camaro has aftermarket light weight control arms, brakes, spindles and axles. I also removed the front core support and inner fenders etc. and replaced them with a chromoly tube light weight front end. It still has steel fenders but does have a fiberglass hood. The engine transmission is 5" higher and 6" back from the stock location, The front seats also sit back 6"

The rear end is also modified with a light weight 4-link chassis that sits 2" higher than the normal install height. It also has a 9" Ford rear end with a lightweight 3rd member. Total ride height is dropped 6" from stock for better aero.

It will be a new light weight dry cell battery.

It will go in the back on the passenger side below the tail light.

Sounds like the pre-runner S10 Blazer I often daydream about...
