1971 318 build
3.55 gearset in an 8.75 rearend.
Before we order anything we will do more research to achieve those numbers.
I think the motivation for my son is him wanting a car that would rival my big block duster and my wifes srt8 challenger. Lol.
When you see your young child running towards the street, do you not yell and scream and race out to stop him?
You can't touch a BB Duster with a normally-aspirated 318 and 3.55s, but um, Hey what do I know.....
What I know:
Big cam= big rpm= in a 318,hard to make cylinder pressure with.
6800 with 3.55s is ~58mph in first gear with a 2.45 low gear. Top of second is 97 mph.
Yeah rival a BB Duster? It's not gonna happen.
32mph in traffic, is um; 2050rpm in "2", and 3460 in "L" ;
In second,the cam is not yet out of reversion.
65=2870@zero slip with an 85" roll-out. Could be 100/150 more with convertor slip.
idles like a top-fueler.
Nice weekend warrior.
yippee.
But hey, lets let him run......
I get accused of spending others money. But you guys want OP to blow a stinking huge wad on machining; then a new set of rear gears, installed; and a really big for street, TC.
But I'm the bad guy for trying to make an affordable combo, (to try to rival a BB Duster), on 3.55s, that you can drive all day every day, and idle in traffic, all while sipping 87E10.
I am not a 318-hater.
I just see the limitations in this endeavor. It's gonna need a BIG solid-lifter cam,which automatically means BIG Scr, and a BIG TC, and BIG rear gears, and then it is gonna have to 60 ft down in the basement, and it will need all the usual supportworks. So add it up; this is BIG money; there goes the College-fund. This takes a lotta love-for-318, to chase after. From zero to 60, like a streeter, horsepower means almost nothing
And you make me out to be the badguy!. Ok; let him run...... Maybe there's no traffic out there today.
Op, whatever you do, don't use that Eddie cam. Rumble mentioned a SFT "aggressive" lobed cam , and he is right. Very aggressive. A lo-po BB, lightweight Duster, might trap at 115 or better, maybe 118, which at 3400 pounds of street weight is 400hp. So yes, you can build a 400hp 318, looking at 1.26hp per cube. Just open up your wallet and spend. A 360 might do that at 1.11, with just a lil compression, and bolt-ons.
But horsepower means almost nothing from zero to 60 when handicapped by gears and stall. That makes the 360 the clear winner on the street with 3.55s.
