Where are the casting numbers located on mopar heads?

Before I start, please accept my sincere thanks to all of you for your advise and suggestions. Its nice to know that I can relate to someone or something even if it is on the net. Thanks all! Now to my biggest problem- HEADS I have a low mi 318 LA from a 71 truck. I would like to get about...

Hey all, I am kicking around ideas. I have a great low milage 71 LA 318. The Mach shop I use stated that I could use HP/Comp pistons to increase the comp ratio. Is there a set or brand or even a part # that any of you have used the you would recomend or condem? If I bring up the comp ratio, will...

Hey guys, I just left a u pull it place and found an 81 D150 with a 318. The strange thing is it had a 4v Manifold. Did Dodge put this on the 318 trucks in the early 80's or is this something some one added? I put a picture of the casting numbers with this post. Brian

I found a hi mi (march of 91) 360 at a local u pick yard. Is there a way to tell if they are swirlport? It has a old TB injection system. If I put these heads on an older 318 will I have trouble adapting an Eddy manifold w a carb to it? If I use these type of heads will I get 10 or more hp on...

I am using stock heads with stock pistons. I found a really great deal on a 71 318 that had less than 20000 mi. The inside of this engine looks like new. Therefore, I really hate to get too deep into mods. Thats why I am keeping the stock parts. However, I am going to use your idea of a mach...

Hello Everyone, I’ve been reading too much! I bought a Comp Cam (Flat Hyd) and some new roller rockers for a 71 LA 318. The specs for the cam are as follows. Intake 462 Exhaust 482 with a lift of Intake 275 and Exhaust 284. The roller rockers I got are 1.6:1. Will these cause problems with too...

What are J jeads and what models could I find them on?

I am building a street engine. I want the most bang for the buck. I have a good 318 an I am trying to get the most I can from it. THe article also mentioned that I would need to get .060 milled from the heads of a 360 to use on a 318 to over come the low compression ratio. Does that seem to help?

I read a few pages of How To Build HP Chrysler Engines by F. Adkins. He seemed to endorse putting swirlport heads from a 90 ish 360 onto an older 318 LA. He stated that this combo when used with a manifold for a 360 seemed to be a good power house. Has anyone here done this? Does it seem to be a...

Does the Cold air kits from Spectre seem to work? I found a new one for a muscle car and all the related hardware/ hoses NIB for 50. I am thinking about playing with it but wonder if any of you guys has tried it? Brian

Are crank scrapers required for SB's? Is the kit from Mopar Performance (Part #P4529790) good?

What are the benifits of a windage tray in the oil pan? Brian

I am using a flat hyd comp cam. It has a 460 and a 475 staggered lift (I think those numbers are correct).

I just read an article about a guy that used roller rockers on an LA 318 and it was pumping oil from the top of the valve covers. The editor suggested that he use a oil pressure regulator. His rockers are needle bearings. Mine has bushings. Will using this type of rocker cause more trouble than...

I am running a street car with a mild 318 in iit. Would I see a higher hp gain if I tried to use a Mallory Accell or other name brand boxes that are available? What about those e-3 diamondfire type plugs? Do they really work?

When changing from a rear sump truck oil pan to a center sump oil pan (in a 71 318 A body) will I need a different pickup tube? Brian

Thanks for the info. Do you know if a pan from an M body would work? Diplomats are a dime a dozen at U pull it yards. Any suggestions?

Hey, I know this is a silly question, but in an A body, is the oil pan a front sump or a rear? Does anyone have a pict? I have a truck eng (318) that I am putting in a 73 Swinger. Can I simply turn the pan around or will I need a car pan? Brian

Hey everyone! I have a super low mile 1971 318 engine. I am considering using a larger cam with between 450 and 500 lift. How do I raise the compression ratio to higher number? Do I use bigger pistons? Should I have the heads milled down? Does anyone know what the compression ratio is for a...

Thank you everyone for your suggestions and comments. I will process this and post my finding. Brian

I am thinking about using 97 Magnum heads on an older 318 LA. I have read that they do give more power. Has any one done this? I wonder how much more power? 10 , 15 HP or is it good for 5 or less hp? Let me know if anyone has done this and if its worth the money it takes. Thanks! Brian
