Cams for 318's
ok... looking at these numbers in the posts my head is spinning....
another 318-cam Q. 78 Sport Fury, 318, 904, 2.76. warm weather daily driver/ cruiser.
want to wake it up a bit "off the line" So far dead stock OEM except for true duals.
car has 53k original miles I am 2nd owner, Ive had since 2007.
don't want to get too crazy with it still want the wife to be able to jump in and go as she can with it being stock. just with a bit more oomph. I still have yet to delete the Lean Burn, have all parts needed here for that.
I did put an Edelbrock True Roller timing chain in when I did the water pump, just afraid of the original nylon toothed POS at 40 years old. I have an old Offenhauser alum 4 barrel here and a Performer intake (not RPM)
also have a set of fresh from the machine shop, 302 heads. All 16 valves are brand new, along with guides as needed (I forget how many guides he did, may have been all exhausts??? Need to dig out the bill)
I want to put a slight cam in that will actually work in here to do what I am asking, along with those 302 heads and either a TQ or a carterbrock 9511 (500 cfm) or a 9626 (have all on hand)
1st 2 cam choices (because they are here, and that don't mean I "Have to" use either)
Stock 360 cam (dead ringer for COMP 252 except 0.015" less lift) I used one of these in a 318 LA that I also put a std Performer on, new EQ Magnum heads and Hooker Super Comps at the same time. That was in a D250 that was USED as a truck, hauling/towing, the whole bit... huge improvement from stock but that truck also had 3.55s and taller tires
COMP 260 would this be too big for the 318? My son ran this one in a 360 for ~5k miles then pulled the engine back out and apart for a mystery oil eating issue, wound up putting a stroker crank in it and turning into a 408, and went with machine shop suggestion for the now larger engine
I have heard of the Comp 256, would have to scope that one out.... might be a possibility
I put the 248(?) in a short bed D100 w/a '69, 318 Edelbrock "Streetmaster 318" and a 625 AFB/ and a 833 OD and 3.91s years ago as I was "afraid of" the 252 being "too big" way back then.... probably would have been fine. did the "pick a cam and back up 1" in the catalog I was gun shy at the time, because the previous 318 to that was a 77 motor in a '75 Cordoba, all stock except a 4 barrel and (I forget the rest of the specs) an Erson cam (back in the "Super Shops" days) that as I remember (hey that was the 80s, memory is fading) was a .429/.444 cam of I forget what duration, etc that was a total slug. Lots of noise no go.....
have also thought of sending that stock 360 cam that I have to Oregon Cams for a "touch up" and slight grind, as that one too, is used. when I did the one in the 83 D250, mentioned above, I bought a new Melling 360-2bbl "stock replacement" and used the magnum heads' 1.6 RR which won't be the case this time. Found one new in box for like $80, but that was 10 years ago.....
I only got thru 1/2 of this thread previous to adding my post as I have to let my head stop spinning from all the numbers presented to that point....
so to recap/// want to warm up a 53k original mile 318 in a 78 2 dr Fury (B body) and want to know which cam to use with that short block + 302 heads+ one of the intakes I have on hand+ one of the carbs I have on hand...
May eventually consider a gear swap from the 2.76 (I don't think 2.94 would be enough of a noticeable change) so looking to go 3.08 (yes these are available for the 8-1/4 since the square body Cherokee days) or (at most) 3.21. But that's a ways down the road, will stay with the original 2.76s "for now"
right now the car is a bit more doggy than I like but it loves cruising the highway at 70 and is great on gas in doing so.... I don't mind sacrificing "a little bit" of the "good on gas" to get what I want.
