Yeah, start with a 355 built to '70 LT1 specs...tickle it with a 150HP whiff of nitrous...then you're ready for Street Outlaws.

P.S. Weren't we talkin' about inline sixes? Whatever happened with that kid?

You just use the normal hot rod tricks on it And with to days tech you can even go to fuel injection .I have even seen people split the exhuast .There should be some books out there from SA and HP books that may help.

Hmmm, probably because this thread drifted off the subject and he didn't get his question answered and gave up.

Take the muffler off all together. The turbo will be your muffler

Install twin turbo(s) off of two Plymouth or Dodge Neons (K-cars). You have 4.0 liters of engine to feed and the Neon has a turbocharged 2.0 liter four cylinder engine.

Use everything in terms of plumbing as you can hit (waste gates, inter cooler tubes intercoolers, oil feed lines, everything that isn't a four cylinder engine.

You will have to fabricate your own custom tubular headers feeding the two turbos with three cylinders each powering a single turbo. This limits lag time to spool up and will power your car with four to six psi of boost. You will also need to go to port injection EFI with two longer duty cycle injectors on the two middle ports (that feed two cylinders) and two shorter injector cycles (fewer pounds of fuel per hour) on the end ports.

If you ever get it running don't forget the race gas as your going to be adding a lot of dynamic compression. Just keep track of expenses and compare it to a 305 SBC out of a high mile Chevy in comparison to cost. Both will have the same power level. If you want more power out of a turbo charged six you need SBC Siamesed heads welded together to make a six cylinder in-line head a new cam, and forged pistons with deep dishes to keep the dynamic compression pressure down to be able to burn gasoline: or you could burn straight methanol like an F1 race car.

The only down side to a Chevy straight six is it will crack the block between the #1 cylinder head bolt and the water outlet bolt every time it is pushed hard. So you will get good at engine building after a while. I got to where I could pull my burnt up VW engine out of my Karmen-Giha and rebuild it on my lunch hour I did it so often. Six is more cumbersome and a lot heavier (I could yank the mostly magnesium VW engine with one hand and carry it to the work bench)

You're welcome.
Not much of a turbo fan, so I'll bow out on that subject.
Instead, I will just stick by what I originally posted.

You may want to install an high-flow cat-back exhaust system, you can find a wide variety of options all over the internet. My favorite brand is Magnaflow, been using the pipe for 5 years now and whenever I encounter a vibration problem I just simply tighten it.

I have Magnaflow on my 75 and they sound pretty good, just don't like the drone when you're cruising on the highway.

Installing a high flow intake and air filter can do wonders for your car's improved horsepower.
