Anybody running a 422 stroker engine in their f-body? Any problems with it? <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

I seem to go though rear tires sooner <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Mine runs flawlessly. MTI did an EXCELLENT job with my car <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

I'm having some electrical problems right now but have gone 11.1 @ 3600 lb raceweight on pump gas.

 

My first 422 had a dropped sleeve. It was replaced under warranty, with no questions asked. After that, I had some minor tuning issues, but they have since then been resolved.

Now, it is reliable transportation, still very sane gas mileage, and wheel-pulling torque <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I am amazed at the number of compliments I get about the car, especially about the way it sounds and runs.

I love this thing, and am currently in the process of making it even faster. Should have very streetable low-10 to possible high-9 sec car very shortly <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Greg what are you up to?!? <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

9 seconds on motor here. Hydraulic cam, will run on pump gas, and best of all it has a warranty.

Thanks MTI! <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

I drive my Formula about 200 miles per week, and still manage over 21 mpg on the highway. My large cam is borderline rowdy, it has a little trouble finding its smooth idle on a hot start, but other than that it is just fine.

Can't complain about the performance though!

Mike2002, prices on the engines will vary depending on what options you choose. Solid roller camshafts, Jesel rockers, upgraded timing chains, LS6 heads, etc...

expect to pay $12-15K for the longblock in most cases. These come with a 2-year, 24K mile warranty if MTI installs it for you. And they encourage you to race it!

Off the subject, my wife and I should have y'all come over to our place sometime. Could be fun.

 

Just outta curiousity, how much does the 422 or 434 strokers cost from MTI?

LOL! Hmmm....with my next MTI NA 434 engine that wouldn't be a problem at all. No thanks on the 200R-4 tranny. I'll take reliability instead. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

a little off topic but what exactly is the 200-4r tranny, wasnt it in the grand national or am i crazy?

I will add a little history here, if anyone sees anything wrong, please correct me...

The TH200 (later the 200-4R)was a GM transmission that predated the 700.
The 200-4R were first used in 1985 and ended in 1990.
(the plain TH-200 began use in 1976)

The 200-4R was also used in most of the cars (i.e. Montes, Caprices, Regals)

Greg's will be a "built" one. There are many guys that build them up to handle the Turbo 6's power.

I was leery of the 200-4R, until I found out that Mike Kurtz was building these things and having them *live* behind motors making 800+ torque. And by live, I don't mean 5 drag passes, but well over a year driven hard on the street and the track (MTI seems to think pretty highly of these also). The non-built 200-4Rs are to be avoided - would fall apart pretty quickly. Also, the 200-4R is a relatively lightweight tranny that seems to have minimal power losses.

The motor route you are doing might be my project for next year. I am hoping by that time that a *reliable* turbo or supercharger system will be available for the LS1 that can feed a large-cubed motor. We shall see . . .

 

The 200R4 is a light tranny for sure. I just don't know if I trust it leaving on the brake at 6500 RPM. I don't think the case would take it. Maybe a powerglide would be best? Hmmm....

 

BTW, where is Mike Kurtz from and how to contact? Website perhaps?

He is incredibly nice - I spent some time on the phone with him today. He has been building these trannys for over 10 years, so knows them pretty well.

These built 200-4Rs are taking ridiculous amounts of torque for a lightweight auto trans with OD. Talking to him today, he indicated that they are living for long periods on low to mid 9-sec GNs (which are heavy slugs as you well know). He thinks I will have no problem at all hitting it with 900 foot-lbs of flywheel torque <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> , even for extended periods.

The one thing to watch out for is that 200-4Rs may not like transbrakes. Since I am not getting one, I did not check into this extensively, but have heard rumors as such. Mike would definitely know.

Should this post go to the drivetrain section now?? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Mike kurtz is well known in the turbo buick world as one of the best for the 200 r4.my freinds GN was making 700 RWHP and could not kill is 200 from him.Dont forget that if they live behind a turbocharged motor making that much power a n/a or nos motor will be a lot less stress on it.Turbos are tuff on transmissions.
