$750.00? Better check IMCA. I know for the Hobby Stock the pay only $325.00 for a engine claim. I know the class I'm going to be running in will have to have pretty much stock OEM engines & parts. If thats the case, I may just buy higher displacement engines from the junk yard & run those. But then again the engine I choose will have to be available for the car I run, I think the 351W was a option for the LTD.

Running a Ford is a good way to not get claimed 
The picture there was near the beginning of last season.
Last year was our 3rd year with the T-Bird body. The 2 years before that we had a steel Fairmont body on it. We weren't allowed the fiberglass then. That means the car, other than the body, has 5 seasons on it. The body came off a CASCAR car. CASCAR is Canada'a top series. Their website is www.cascar.com
We built the car with the Fairmont body on it during the 1998 season after my wife wrote off our Crown Vic. She got run into the wall. I wanted to build a new car but not quite then. Oh well.
It all worked out ok in the end
Yes, she races too, against the men. The last 2 years she has won top points "B". Last year I missed top points "A" by one point
whine whine
I did get it the year before and set fast time last year too though so it wasnt thaaaat bad

My cars when done will probally look like that #10 car in actuality. What is that anyway, the #10? Monte Carlo or Grand Prix.
I would think running a Ford will be better oportunity to get claimed. That way all the chevy cars will not have competition.

The #10 is a Malibu. Same car underneath as a Monte Carlo or Grand Prix or Regal or whatever.
I've heard that at a lot of tracks engines other than Chevs dont get claimed often at all because most tracks have a rule that if you claim an engine you have to run that engine the next race day.

If you refuse the claim, they take all your points, make you repay all your winnings and strike you from the list as ever having won. In my case, they pooled $750.00 and took the motor. In return, I got to keep my trophies and the $3,200 I had won in the heats and features. However, I was done. That was the only motor I had.

Hang10, looking at your rules I think you could make Ford with lots of power
If I read the rules right you can use World Product heads which work very well or the same GT40-P heads I use. They arent classified as high performance heads. They are the stock heads that a 5.0L Explorer uses and those certainly arent high performance.
You're allowed the same intake as I run and I feel that it's a better piece than what the Chevy guys are allowed to run
I can dig out my cam numbers for you if you want. I got my cam from www.amotion.com which is an online parts store from not too far from where I live. Like I said I run a very mild cam compared to anyone else I race against and turn the engine way lower rpm than all the rest too.
What transmission are you going to run? I run the old Fairmont aluminum 3 speed with OD. It's quite a bit lighter than a cast rion transmission and has the internal linkage which is easier and less weight.

That tech rule really stinks. At our track any engine or car that is protested and teched gets the teching done that night. If it takes them 5 weeks to get around to checking it I think I'd find a different place to race.

I don't recall any of the GM guys being teched. It was a mess. I wasn't well liked. I always had some idiot trying to do something. I had people let air out of my tires. Park a truck behind my trailer and something in front of my truck so I couldn't unload my car. The first week I was there, it was a joke about the "dummy with the old coupe and a 6 cylinder, that looks like it came out of the 50's jalopy race junk pile". I had great fun showing them up.

I sure wouldn't give up the extra 50 cubic inches if I didnt have to. Bigger is better
A 351W is easy to find. Look in old vans, trucks, Crown Vics etc.
A lot of the parts are the same between a 302 and 351.
Yeah the head rule could be read either way. Call and ask.
If World heads are a no-go then I'd try to find some Exploder heads. They really do make a difference.
