which is pretty good considering that's close to triple what they were born with.......

The 225 has a long stroke and a well-supported crank; it's a natural for super/turbo charging. I cannot recall ever seeing a pair of small turbos fit into the available space; the light-weight-A would really sing. Ok, that's my dream,lol.

I think they put that 292 cam in the 380 hp crate motors ..... which were independently tested at ~400hp,IIRC Almost right; the 380s had a 288/292/108 and 9/1 SCR

76* of overlap on the 108 version is a long long time to be blowing gas and air straight across the piston and out into the header pipes. What if it catches fire in there?

And the lower deck fits a lil better in the A-bodies. And IIRC a stock-bore 400, with a 440 crank, and custom pistons, makes a 444 While the 383 and 440 crank can get you about 430 cubes. Connect the dots..badaBoom! Fat FAT midrange.

That's a good plan

...gauge, about. Designed for 7.8Scr, your 273 will make about 118 psi depending on the ICA, (your cam's Installed Intake Closing Angle) ( I chose 62* and 500ft above sealevel. That's my best guess working from memory. Now if your Intake temp is too high (no hoodscoop, no intercooler) you may...

...you bolt on there is gonna drop your compression,IMO, a good thing. Perhaps 62cc Magnums with 1.88intakes. I would surmise tho, that a 273 at 22*total timing is gonna be a dog until the pressure hits. You gotta have something left to drive on before the Super hits, which might be something...

Or about to retire and try to survive until Judgement Day. No infirmity here, but you never know if satan will find a chink in my armor. Threescore and 10; fourscore if by reason of good health. That's 5 to 15 more for me, hardly worth starting another project. Whereabouts is Daygo? BTW nice...

Man, I'm sorry to hear you're hurting physically, and wish you all the best. Well, notadvice but Have you researched 10.5Scr and supercharging? I have never done it, but I know you can only run so much total cylinder pressure with iron heads, and; depending on the cam, 10.5 with a supercharger...

IDK anything about this set-up, but I do know that in order for the fuel to come out of the fuel circuits, there has to be more pressure in the bowl than at the butterfly. So I'm wondering if your throttle valves are open too far and the cranking is pulling air around the throttle valve with no...

2008/DOH

...of time and money on the rear suspension and tires, even 375/400 blows the tires off, in second gear, at 50 mph, with 3.55s. That's an LA 367/ 230* cam, Eddies and 180psi. And same engine goes 93 in the 1/8th with a 2.44plus 60ft..........@3467 pounds. so I gotta wonder about the 600hp...

Illegal on Manitoba roads; too high. We can't hardly run Tunnel Rams

3/8 steel is good to 400/425 in my NA 367, with a mechanical pump and no return.

Ok you got my attention; What's your secret for street hooking? I have: Starter gears of 10.97,or13.29 ,or15.08 (3.55,4.30/4.88s and a 3.09 first gear), a CFII clutch, and up to at least 400hp/420ftlbs/crank. I have a GVOD,wired as a splitter, so I can carry that peak power out to about 40/45...

...the power delivery is rather linear, predictable, and repeatable.My engagement window is from idle to maybe 3600 typically. The power with my 230* cam doesn't really wake up until over 4000. That is to say the climb is a little steeper after 4000. Now try that with a roots. Firstly, with...

Sure you can blower that 340. If it means making your dream come true. But you're gonna need to spend some money on the chassis to get it to hook, cuz if it don't hook, you might be big-time disappointed. Cuz then it might as well be a teener. If you just want a cool looking ride and don't care...

I did the 292/108 thing in my 11.3Scr-367 for a summer, and it was dynomite from 5400 to 7000. In the end tho, that cam suffered in the lower Rs where I spent most of my time, and the 367 was not strong enough down there with 3.55s. I tried several different chunks I had laying around, but in...

Zachary A supercharged 416 is a great dream, but I wonder if it's practical. As a street car you have two problems; traction and speed limits. A 416 with a roots will just annihilate the tires and then it's over. A 416 will just annihilate the tires and then its over. A roots on anything will...

I love happy endings

If you machine it flat, you may have to also machine the stat-receiver shelf. If left too shallow, the stat will cut the gasket, and prevent the sandwich from stacking flat; and that will cause the freshly machined housing to warp as soon as the bolts are tightened. Pressure test it before the...

staged turbos. Oh sorry , that wasn't an option.

60,000 is just nicely broke in, just put a new double roller chain on it. Sneak up on the boost while you sneak down on the tune. But above all take those turbos apart and rebuild 'em before you bolt 'em on. China doesn't charge extra for the debris they ship along inside of them. That's...

I'm old and broke, semi-retired. My dreams are dying.and so is my ambition.and energy. You could take over my dream.............................

You paid for that heat. You want to make it work for you. That means to keep it where it belongs,namely, in the chamber. If you get into detonation, aluminum heads is not the best answer.

cast-iron is better.

Yes and yes;the post was edited while you were typing. But you can probably run up to 360hp in the 8.0 factory holes, on 87. I have always wanted to run a teener on dual,staged turbos, a little one up front,to get things rolling and a bigger take-no-prisoners kindof guy remote-mounted,out back...

Ok here's something else; you said My 367 goes Zero to 93 mph in 7.92 seconds with a 2.2 60ft. The speed limit around here is 100kph or a tic over 60mph.Guess how quick this car might be to 60 mph, if I spent some money to 60ft decent? I'm guessing that would be a low 5 seconds. Now try and...

Evan, dome pistons and small chamber heads are backward for a turbo The less Scr you have, the more boost you can run. The more boost you run, the more power you can make. Sooner or later, the looooow Scr will become a problem off boost. So for a streeter,the trick is marry enough off-boost Scr...
