Wow, that is awesome man!
The Cuda sound like the Challanger from 2-slow 2-gay?
Is that what GTO's, 442's, etc sounded like also, or not "THAT" powerful?

Cuda sounded a helluva lot meaner then most of the chargers/challengers I've seen, stock...maybe he had different mufflers, I don't know. It wasn't so much loud as just incredibly deep and menacing.

A lot of GTO's have that same sound, though the "original" exhaust system on most has been replaced already so its really whatever noise level the owners desired. Love those cars... They just line up in a big row next to the road I cruise/race on... Most of the time they just sit there, but every now and then they'll come out and tear **** up for a few laps. Simply awe-inspiring.

So you are saying that most people didn't replace their REAL American Muscle cars w/ the original exhaust, but put quieter after-market on them?
Wow.. that would be so KICK-*** to have all kinds of American Muscle lined up along a road often traveled (By me, I mean..).. that WOULD be awe-inspiring!
I also LOVE those cars, man! They are so ****in' awesome!

That link did not work, Zepher.
BTW.. I checked more of your videos out today.. DAY-UM!!
The one where the car is just siiting in the driveway idling, then you start revving it up.. NIIIICE!
And the one where all the Muscle Cars, and the Crapota ****ra is doing donuts, is awesome, minus the ****ra.. Keep 'em coming Manny!

That Supra is fast and it's going to be really fast really soon.
700+hp from a big turbo.

250hp in a 305 is cake, do the victor jr./edelbrock TBI i thing, but try to find them used on ebay, or post a parts wanted ad here. now, just throw in a comp cams Xtreme Energy camshaft with .495 int\.502 exhaust lift, have a valve job done to the the factory heads and have 1.94"exh, and 1.60" int. valves . put in new valve springs, locks and retainers. If it were me, id get a performer RPM or performer RPM Air-Gap instead of the victor jr. intake. The vicotr Jr. will rob you of alot low end torque. you need more low-end torque in a street car. Headers wouldnt hurt either. This is pretty close to a 300+ HP setup.

parts will probably run you around $700+Headers
Labor will depend on where you get it done at.

Thats my 2 cents, Gene.

My personal recipe for my 305 buildup is...

400 crank and rods
ported Vortech heads, with a performer RPM air gap to match
gm Hot Cam with 1.6 RR (hyd roller cam)

should be around 400 ft/lbs of torque, 300-350 hp.. and I have a little Cheater plate around here somewhere..


Why you say?

Because I like to be different, and I am working with some odds and ends I already have.

Plus, the smaller bore on the 305 tends to get a little bit better MPG than the equivilant 350, and since this is going in my daily driver 70 Z28 project (with a T56 6-speed), might as well make it fun!

Never underestimate a "lowly" 305!!

The ****ra may be fast, but I still don't care for it because it is overpriced, japanese crap, that is pretty damned ugly in my opinion.

I wouldn't really call it japanese crap. If you ever have the opportunity to drive one, drive it, and then tell me if it is crap.
It may be overpriced, but they hold thier value pretty well.

They have incredible handling, and when slightly modded are fast as hell. They are really fun to drive, especially with the targa top off.
I can't wait till I can afford to put a pair of turbos on my 86.

Ah.. they "do" have good handling.. I thought they did, but was not positive.
Are they fast stock? What are their times?
What about the ride, any good? Interior.. etc..

They are quick stock, not too fast. 13.9 @ 105mph bone stock 95 Supra TT Auto.
$2.00 t-bleeder mod and it went 13.2 at 110mph.
Downpipe and exhaust and it went 12.8 @ 117mph with boost problems.
Ride is very good, interior is like a cockpit of an airplane and is centered around the driver,


On the highway, the Supra really shines. I've had it up to 165mph and the car was still pulling strong, I had to slow down since there were cars ahead of me and I was coming up on them really quick.

Here is a nice pic I took while cruising down the highway to a hangout one afternoon.

took this pic while riding in my friends 86 Z28.
