Engine size change
I have a 1978 Mercury Cougar with a 351w 2brl that should run in Q/SA. I would like to know If I could change to a 302 2brl and run U/SA?
If I can change to a 302 will the short block have to be a 1978 or is there some leeway on the year? I understand that the Intake, carb and heads year and model specific. I'm new to the Forum Thank you for your help. |

yes you can change the engine, the block does not have to be from the year, but the pistons have to be of the same compression and configuration. What part of the country are you? |

Re: Engine size change
Go for it. Based on the ET of the U/SA no. 1 qualifier at Indy you should be able to run -.68 under the U/SA index if you keep the car at factory shipping weight. If you take out 300 lbs, you would be -1.00 second under and still be 700 lbs heavy for the class.

Re: Engine size change
Good luck on your project. I would get ahold of Brian Seaberg. He lives in Belfair Washington. He is on here - user name is B/S 428. Brian runs a 72 Comet in U/SA and that car is fast. He can help you as much as anyone locally. Brian is scheduled to be at Las Vegas this weekend. Again, good luck with your car, sounds like fun.

Re: Engine size change
Lotta Ford stockers out here in the NorthWest and a well organized Stock/SuperStock Combo series run at Pacific Raceways (primarily) with some runs at Bremerton and Woodburn, Oregon. Build it and run. I hope to sneak my Mustang in as SS/CS if I get it right.
Unless you intend to run just NHRA National and Lucas Oil races for points and Wallies, I think the emphasis on the hunt for the most competitive package is over rated. A good combo like a Formula Firebird or Comet might get a by as number 1 qualifier, but beyond that it's all a bracket race. As another retired guy, I'm done with the stands. Give me the lanes.

I hope nobody thinks the no. Q at Indy has a 2.45 low C4 with a rebuild kit in it...? You'd be able to buy 5 of the right cars for a 302 2v, for what a trans would cost to make that Cougar work @ 800# overweight. If you don't have a 302, get one along with a body style that weighs less than 3000#. 351 2v , no bargain either. Might run a few under in R/SA ..Still a two ton tank. I'd suggest putting that Cougar away with the family heirlooms, and let's get serious here.

Re: Engine size change
Dale, I don`t see anything on the Pacific schedule about this. I see on NHRADIV6 the National Opens are in Bremerton, Mission, Edmonton and Medicine Hat this year. Is there something different that you are referring to?
