Re: AFR tuning 351W carbed 69 cougar

My replies are mixed in your quote below. [quote=9F91H581221 post_id=124346 So if I understand correctly - Idle around 14:1 like it is now is good? I try for the leanest idle without compromising smoothness. The engine in my Colony Park wagon has the MSD Atomic EFI. 14.2:1 seems to be as lean as I c...

Re: AFR tuning 351W carbed 69 cougar

I wouldnt change timing. Your cruise sounds like it could stand to be slightly leaner. Acceloration is lean. But, it depends the level of acceloration. Do you mean light acceloration, normal acceloration like in regular traffic or hard/fast acceloration? Monitor your a/f at those three levels. Are y...

67-8 drove past my house.

Hey guys. Last week my neighbor yells my name and says "Look! Look!" a silver or silvery-blue 67-8 drove past my house. It had NY plates. I only saw the back end driving away. He said he saw traction bars on it. I'm in North Adams, Mass. About 45 minutes east of Troy, NY. Was that anyone here?

Re: Header recommendations for 351-2V

25 years ago I put on Blackjack. 10 years ago I put the cast manifolds back on. If I wanted headers today it would be FPA.

Re: rust prep recommendations

Is it known if Evaporust can be diluted? I was planning to find or build a box big enough to submerge some bigger parts like back seat frames and maybe even a door.
If it can only be used strait, I might have to consider a 55 gallon drum.

thanks.

An Autolite or Motorcraft 2100 would work well too. What carb do you have now?

Re: 500 CFM for a 351c street car?

Totally agree except for the 750. It will be too much. If you do not have your foot in it and go up above 5,000 RPM a 4V is a waste of money. 9F is right on the money! Looks impressive but without fine tuning you will realize very little. If you have plans in the future to go further such as a cam ...

Re: 500 CFM for a 351c street car?

Emotionally, you want a 4 barrel because it could mean more power, it's more impressive to look at and it is perceived as an upgrade above basic. Logically, it is a waste if money as you wouldn't notice a 10 hp gain in an rpm range you don't use. Simply bolting it on is not the end. To do the job th...

Re: 500 CFM for a 351c street car?

Either 500, 600 or 750. You won't notice a difference. For Edelbrock carbs, get one that has lean jetting from the factory. As I remember the ones that come with electric choke have a leaner setting. It will still be on the rich side for your application, just not as rich as the manual choke versions.
