I wouldn't call it a disadvantage, call it a challange,
First off, Is there a weight rule? The GM h-bodies are a little heavy,
Is it a dirt or paved track?
What engine do you intend on running? Do you have the 2.5 Iron Duke?, They cost more to build then lets say a ford, But From what I understand they can be fast, if you spend the $$.
I myself run a Monza, 1/4 mile dirt track, I run the 2.2 engine, no distributor, crank fire, very fast, very dependable, Again more $$ to build.
Bottom line is can be competitive if you are up to it.
I have two Championships to prove it.. The weight thing could work for you or against you, If there is no rule then it will be hard to get it light enough.

200 lb weight break, 1/2 mile high banked dirt. as far as the engine goes i dont know haven't got that far into it yet. the whole team pitched in a few $$ and they're gonna play with it. We have a pure stock that we're running for the points this year and were ready to see that 4banger run

I havent seen the chevys run myself but I was about to buy a monza myself when i talked to a couple of people they said they were fast but they were hard to keep on the track because they couldnt keep there motors together. Like I said I havent seen them run myself so thats just through the grapevine.

my cousin used to run a chevette and that thing was fast but It was not like a ford you did not want to turn the motor real hard. My dad also had a chevette at one time and it had the little I believe 1.8 engine and it saw 8000+ every week and was fairly good for a stock class. Bobby

My engine is going into its 6th. season, freshened once, turn it 7700 rpm. protected by a rev. limiter, granted I haven't raced it every week, but I ran it at least 50 weeks before I had it freshened up, Pay to have it built right and it will last, I put around $2500.00 into machine work and pistons.

in case any one is interested 151 iron dukes should have the same rod/piston sizes and lengths as the 77-78 301 pontiacs,olds 350 valves work,chevy springs/lifters fit also. a little research should yield quite a few other inexpensive combos. if it's close it might work

If any one is interested I have 2 151 iron duke motors for sale. Dyno sheets for both motors have over 300hp. I need $4000 for one and $5500 for the other. Check your rules. Motors have aluminum heads. Have had to race these 4 cyl motors against V8 Late Models for the last two years.

Disadvantage - are you kidding? youve got better suspension all around. the ford guys only wish they had your setup. build the motor right and you'll do fine. go to gmpartsdirect.com and check out the hi-po parts for your "iron duke".
also - check out the 3.0 mercruiser boat engine(GM). go up to 181 cubic inches with just a crank swap and piston and rods. cant beat it.

I dont know what kinda of setup your talking about but the setup I have is perfect I couldnt ask for anything better.As for you chevy 4 bangers I have never seen one beat a ford 2.3 and there will never be one that will. If the chevys were so great then everybody would be running them just like the small block 350. the only people I see run the chevy 4 bangers are the guys who cant afford to run every weekend then when they do show poor them aint pretty.

Jammin James,
The casting and part number for the GM-Pontiac Superduty-4 racing block is 10093306. This is the same number used by Kansas Racing Products when it manufactures the replacement Superduty-4 block for GM Performance Parts. The Ford casting and part number is M-6010-B180. The Mopar version does not have a casting or part number.

You've never run against one of my Chevys!! LOL

the first problem is availability. fox chassis mustangs have been around since 1979.
the gm cars are hard to find in most casesbecause of low production numbers.

the front on your mustang 3 has a mcpherson strut front end - the gm has an unequal length control arm configuration. the same as all real race cars in the world. the mustang has a 4 link rear suspension. the gm has a torque arm rear like your cup cars have. car to car comparison the gm wins hands down in the handling dept. if you build it right - you'll be in front of all the ford mustangs (2,3, and pintos).

Hey Speedyd1,
Thanks for the boost. Don't beat 'em up too bad or they'll make you illegal or have to weigh 4000 lbs!! Of course if they really want to use a Ford, they can always acquire a KRP with a Yates Winston Cup head or a KRP Mopar with a W-5 head.

Hi Jammin James,
Actually, Chapman is about the same size. Still mostly a farming community with some individuals working in Junction City or Abilene. The Kansas Racing Complex with the Kansas Auto Racing Museum, Kansas Racing Products and the Covenant Race Teams was constructed on the north end of town towards I-70 about 3 years ago. You are welcome to take a "virtual tour" of the Museum. Go to www.linktokansas.com then open the Virtual Tours link. Scroll waaaay down the the KARM site and click on the photos or the black IPIX circle to load the tour.

Regards,
Gerry Dedonis

You might check this source: http://www.aera.org/main.htm or contact Billy Page Sr. at 903-569-6311. Billy had raced the GM engines for years. His choice for stock blocks were the 1979-80 Pontiac Omega or Chevy Monza...both rear-drive cars mated to a 1987-92 head.

There are at least 6 variations of these 2.5 engines built over the years. Stay away from any that came from a front-drive application.

If you want to make these into "stroker" engines and raise the displacement to a 2.7 or 3.0, you can install the 3.25" or 3.6" crankshaft from the GM marine or industrial engine. You will need to have wider rods (1.029) and install a rear-seal adapter made by Billy Page. I do have crankshafts available.

Gerry
