There is a bunch of Boss people around here so you should be able to get all the answers you need.

Welcome aboard.

A few years later with a 350 chevy & 3 speed manual with a very poor choice in color.

And then a while later...  



Then making a really bad chop job less bad... Not good, just less bad...





And now with the blower gone and a 5.3, turbo & 4L80e.

The car is now on a shortened GM metric (S10) chassis so it isn't as bad as a Mustang, but header fit is still going to be a problem.

Once I spend $5K on the heads I am probably going to be willing to do whatever it takes to make them work...

Nice looking car and good job on the chop, it's hard to get rid of the hump in the back. How much did you take out of it?

Right now it has its 5th engine and 9th transmission setup.  The third engine was a 460, but it was basically a stock Lincoln motor with low compression, stock intake, stock iron exhaust manifolds... it really wasn't very powerful and the cooling system didn't really work very well, so I eventually sold the engine & transmission and then parked the car in my parents barn for about 10 years.  No pics of the 460, I was in college then and more interested in burnouts and beer than taking photos...

After letting it sit for way too long I decided to start driving it again as sort of just an old beater without trying to fix any of the messed up body work or rust...



Then I started drag racing it and decided I wanted it drive it to the track and get it to run in the 9's so I made some cheapish changes. It never did better than 10.30's @ 140, but my next engine should probably be able to fix that issue...



Since it has a lot of rust and crappy bodywork I didn't mind running it for fun at the salt flats... I recommend going there with a car you don't care about too much, it makes it way more fun.  



Then I melted a piston in the 496 trying too much ignition timing with a homemade meth injection system....I sold the 496 I installed a 5.3 with a single carb... it was a big disappointment.  The 496 was over 700 whp on 87 octane.. the 5.3 was less than 200 hp... it only lasted about 500 miles and I started changing it to efi & turbo.  



The current turbo 5.3 & 4l80e setup is so cheap I can beat on it with zero guilt, but it really sort of boring.

480 whp is ok but never going to get this car into the 9's, and I always thought 426 Hemi's and Boss 429's were cooler than chevys.

Boss 9 521” for 15-20 psi boost with 10.5 static cr and 7500 rpm limit. With a big block Chevy this would require a solid roller cam, I assume it is the same for a boss setup? Do boss heads actually require different lobes than conventional heads?

the cam and short block is the same other than the pistons.you will spend almost double on boss heads and rockers,valve covers,and intake over a trick flow A460 heads set up,maybe more power, but the wow factor is there with boss heads.check out jon kaase website.also there is the TM boss heads, and also for max power the C and C motorsports has all the stuff you would need.
