As you've seen in my past posts i'm beginning to round up parts for a 360 to make 'er into a 390! was just wondering if i went to a yard, what year make and model cars/trucks i could look for to see if they would have 390 parts. especially the 4 brrl intake is what i'm concentrating on right now. my machinist says he can get me the crank from someone else and he's got plenty of 390 rods. also i'm really hesitant to purchase an intake off ebay b/c who knows how it's been treated in the past handling (dropped, overheated,warped etc) so i'd like to get one i can look at myself before buying. also the other thing is that i'd like to find a surefire way to figure my compression with all the things i'm going to buy. i really really really don't want to have to run premium after spending $1000 on this project . Thanks for any info available!
Just about every car and truck in the 60s had a FE available. Trucks up to 1976 cars stopped having FE's in 1969. Pretty simple, just look for the distinctive intake under the valve cover, then check the number of barrels.
Ok, look in 1960's cars, and F250 and F350 trucks, from early 1960's to 1976. Either the cars or the trucks will have the 4 barrel intake, although you will find more than a few trucks with 360's and 2 barrels in them. Now on the intake, there was a 4 barrel truck version, and a 4 barrel "S" code version used on cars. The "S" code version flows a little better, but the truck version will have a little more port velocity and produce more torque. The difference is minimal, so choose based on your priorities, horsepower = "S" code, torque = "truck".
On the compression, have your machinist figure up the CC's for your head's combustion chambers, and the CC's for the valve reliefs on those pistons. Then measure deck clearance. Then we can figure up compression. Let me say, though, that I HIGHLY doubt you'll need to run premium, if you know how to re-curve a distributor and set timing. Also, you'll want to run a bit cooler spark plug, than the 360's call for. The number RF9YC seems to ring a bell.
1970 passenger cars also had FE's. Think a few full size 71's had 390's also. but that was it for cars. Also to note the "T" intake indicated as a truck only item was also used in cars. And some "S" intakes have been found in trucks. So there goes that theory....LOL. Ford used what they had at the time to meet production schedules.....G.
so what vehicles do i stay away from that have the "ft"'s in them?? isn't that the heavy duty dump truck style motors with heavy duty components?? thanks
