Bigger is not always better. I've had numerous cams in this same engine. It is a standard bore 74 360 HP. I once had a MP 284/484 in it a long time ago. It sounded wicked. Never changed the stock springs. Also had a stock converter with 3.55 gears. Bad combination, too much cam and not...

Im running that exact cam in my stock 74 360 right now. Been in there for a couple of years now. Sounds great with stock exhaust. Still running the original valve springs. Never had any problems. Sounds a little healthier when compared to my dads 70 340 with a factory grind purple shaft...

Last time I had mine out and apart, I checked from deck to center of dish on piston and it checked about 1/4" down in bore. Of course the edge around top of piston wasn't that deep. Mine are KB hyper pistons stock replacement.

ok, thanks moper

Hey guys, need some help. What is the going rate on pulling, teardown, rebuild, assembly, and install of a small block in a 69 swinger? There is a local guy that wants to know what I will take to do it? Any ideas you could give would be great. I've pulled the engine out of my Duster numerous...

Had same problem recently. Tried to seal it twice. Never could get it to stop leaking. Mine looked just like yours, too long. I found a factory mopar seal that I got from somewhere. It fit perfect. So far no leaks after about 600 miles. The fel-pro would leak after about 3 miles. Go...

What does everyone else do? Leave oil pan gold iradated or paint it engine color? If painted, anything special done to keep paint sticking on it good? Pics would be nice. Thanks.

While I've got the 360 engine out and re-gasketing it, thought about my intake. I've got a few selections to choose from. The ones I've got are: casting number----3698434--original to car, spreadbore with EGR valve 3671918--1973 340, same as above but without EGR...

Hello everyone. Replaced my cam thrust plate with a new chain tensioner plate P5007709. Is there anything I should have done different before I put the cover back on? Read somewhere that it is a good idea to drill a 1/64 hole in plug for lifter lubrication located behind plate and drill hole...

What length pushrod would normally be needed in a LA360 with 273 adjustable rocker arms? Thought about putting these rockers on mine since I have them lying around. I have a valve tapping sound. I placed a straight edge across the tips of the valve stems and all of them are not the same...

redfastback is correct, it is part of the emissions systems. Some cars had it but some did not. Mine is an early 74 model 360 car and it didn't have it. I have seen a lot of 74 /6 and 318 cars with it mouted up on the fire wall along with a vacuum booster mounted on the passenger valve cover...

Also, how about some help with my oil leak. Seems to be coming from rear oil pan seal. Tried twice in car, but no luck. Thats why I pulled engine. Looks like seal is getting split lengthwise and wants to bulge out. I'm using Fel-Pro gaskets and seals, but seal seems to be a little long...

Are my calculations pretty close on the compression ratio? Factory it was rated at 8.4:1. Am I anywhere close to that now? What about the pistons being down in the cylinder??

I pulled engine out and pulled it apart to re-gasket it to stop aggravating oil leak. Pulled the heads off to look at pistons. I forget over the years what was in it. They are kb 1279. They are a dished piston similar to the originals, but they seem to sit way down in the cylinder when at...

that is a small block engine kit number

Does anyone know which head gaskets come with the mopar performance engine gasket kit (part no. P4120692)? Also, is there a one piece oil pan gasket for the LA 360, 1974 model block? Thanks for the info.

it dont run that bad. It is lacking a little on bottom end torque, but it is better than it was with the purple shaft 268/272, .450/.455 that I did have in it. What can I do cheap to it to help it more?? I have 3.91 gears and a fairbanks 3000 converter that goes about 2600 against the brakes...

yeah, it was replaced a couple of years ago. I installed a extreme energy 268 comp cam with a comp timing chain aligned straight up. The pistons are stock replacement. It was rebuilt about 15 years ago, but only has about 20,000-25,000 miles on it. Was going to pull out this winter to clean...

What is a good cranking pressure for a low compression 360? Mine is running around 130 psi. I was wondering if that is normal or on the low side.

Ok, thanks for all the input. I chose the xe268h because it wasn't too far off from the original cam. It came factory with the same cam the 340 was delivered with; 268/272 dur. .429/.444 lift. The comp cam does have considerable more lift. I'll check into these different things this...

it seems though if i advance my timing anymore,, it feels like it surges going down the road. Does my timing settings sound about right (initial, Mech adv. , and total with mech and vac. advances)? I checking these at about 2500-3000 rpms and initial at about 800-900 rpms. Thanks Barry

would low compression affect the vacuum reading? Thanks, Barry

Initial timing is 10 deg. mechanical takes it to 32 deg. mechanical and vacuum takes it to a total of 50 deg. Also, my vacuum at idle at the base of carb is only 12". Does that seem about right?? Thanks, BarryC.

timing is at 32 on full mechanical and vacuum advance brings it to 50. I'm lacking just a little on full throttle, because of passing gear linkage. It isn't enough to hurt anything. Not sure what my compression is, but the best I remember about the pistons, I'm pretty sure they are a full...

I could use some help. My 360 is a dog. It has been since it was put back together about 14 years ago. I had to piece it back together after blowing the bottom end apart and not having the money to build it to go really fast. It is together with stock replacement internals except for the cam...
