I picked up a 68 Coronet 4 door back around September. I just really started wrenching on it when i have some spare time. Progress so far....

 

Rebuilt stock bottom end 360.

Rebuilt 2.02 1.60 heads with mild porting, SS pro flo valves, milled, etc...

High rise dual plane air gap intake

Hooker super comp headers

2.5 mandrel bent exhaust kit ( from summit...fit like crap)

Rebuilt Carter 625 carb

Middle of the road Mopar purple cam

 

TCI shift kit with TCI 2500 stall

 

New 489 sure grip with 4:10's (that a posi-trac for you GM boys)

 

Also sittin on every suspension component waiting to be installed. (in a week or two)

 

Interior needs some woth and i'm still waiting to grab some rim and tires

still no dice on the car. I'm throwin parts at it left and right. Just replaced the old orange box and ballast resistro with an MSD, new distributor, plugs..... Still have to clue what's holding it back engine is new top to bottom, ignition system is new, stall convertor is new, rear end is new. timing is set at 36 at 3k rpm vac plugged, carb is set up....


I"m going to run a compression test on it and see what the cyl. pressures are make sure i don't have a dead cylinder or leaky valve...i don't see it though engine idles nice and revs up great in P or N but struggles under load.

what is your compression ratio? if that is the original motor then your comp is only 8.6 to 1 which will make it a dog with that cam,intake and headers

IDK my exact compression ratio. I did shave the heads quiet a bit and the have smaller chambers than the original.

I figured my compression ratio worse case scenario is a 9.16 best is 9.45 (idk actual amount milled from heads. So between 9 - 9.5:1.

I figured for stock bore and stroke. 72 CC heads, .039 head gasket, flat top piston, and a deck height of .070 in the hole with .020 milled on the heads. I don't think it is a compression issue.... I'm going to run a compression test this weekend and see if all the cylinders are good and the valves are seating.

see if the timing chain is installed correctly. take it further and check how the cam was set up with a degree wheel. i found some that were up to 8 degrees off. that will make it a dog.

checked the compression ratio... pretty much 140psi across the board. Install a slighty hotter plug and opened up the gap a little. Seemed a little better but still not all there. I"m gong to try swapping out a carb later today. If that doesn't cut it i'm back into the engine. :(
