318 upgrades
Yeah, you'll be doing the rear weather you like it or not! LOL
The 4 speed can kill a 7.25" quick!
The motor? Tear it down and check everything out, replace gaskets...maybe a valve job and some cleanup done on the heads and a decent cam with matching springs.
What Dave said.
In addition, this is what I did to my /6-318 swap engine.
A 1979 - 318/904 was used. It receieved a tear down, new cam bearings and reassembled with MoPars gasket kit and the OE steel head gaskets. The MoPar box kit has thicker head gaskets so I opted to not use them as to retain what little compresion I have with the smog engine.
Then, it was a Holley 4160 (600 cfm) converter to a 4150 which you need not do, but suggest it as a worthy item to do.
Edelbrock LD4B - an excellent intake for this. A Performer will do just fine as well.
Hooker Headers into a generous 2-1/2 inch exhaust kit from Jegs which is real nice and the price was great.
Cam is a Crane (To bad there outta biz) and it is a split duration spec'd at;
216/228-.454/.480 on a 112.
I deleated the A/C from the car and used a /6 pulley to get around the issue it creates and a electric fan to free up a few ponies.
Nothing to the trans, though a Trans-Go kit awaits.
Shortened the drive shaft to fit the slightly longer 8-1/4 that replaced the weak 7-1/4. The nice thing here is, the 8-1/4 came with a 3.21 gear sure grip equiped rear.
New shocks and leaf springs, 225/70/14 are on the rear.
The carb and distributor were ruffed in for a daily driver status. It could have been better. But;
Untuned on a cold Nov. day up in southern Jersey (Atco) it ran a 15.14 @ 89. :cheers: There are high 14's in the car. Between the shift kit and a decent tune and not so danm rich, she'll run the time into the 14's.
The reggie has the car at high 2800 lbs. The 8cylinder added some weight there. Another 200? 180 lbs. for me, half tank of gas at time of the run.
This is what you can expect from your is the engine is in good shape/trans shifts fine and the gear ratio is what I have or better. (3.55's would be nice)
Have at it, have fun.
