I have a 360 stroked to 408 that is running a comp cam .575, .575 lift and .308,.308 duration. Currently i am running 1.5 rockers and I am considering going to 1.6 rockers. Was wondering how to figure what the additional lift would be if I were to make this change. Also how much if any would...

Ive got a stroked 408 in my Dart. When I decided on building this car I made up my mind to use a 2x4 setup. However I wanted to start the engine with a single 4 bbl just to avoid any issues at startup. Ive gotten evrything else tackled including the overheating I was having so im thinking it...

I have never put a motor or had one built that I didnt start within a month of getting it together. However I think the one I put into the Dart is going to be some time before I get to start it. I was hoping for a March or April start but time is running out as March is almost over. Once April...

I put my covers on tonight with the gaskets that were in the overhaul kit. These gaskets are a hard fiber type. I have always used cork gaskets on my cars in the past. What are the thoughts for the best sealing. Not looking to have any oil leaks once this thing is started. Heres a pic of the...

I know the bottle neck in the motor I will be running in my dart is going to be the 915 J heads. I did step up the valve size when I had them redone. So heres my question: What does a 915 J head flow stock? how much more with the larger valves. And how much would I improve the flow if I...

I bought a set of aftermarket valve vcovers and put them on tonight to see if I would have any issues with them. Well I do! They are aluminum covers with a bottom flange that appears to be hitting the springs. Yes they are not a stock spring and the heads needed to be cut to use them. I was...

could someone please explain what is meant when they say the Cubic Inches will eat up the cam. I am stroking a 360 to a 408. So many people I talk to will say the cam will act a little smaller because of the motor being stroked. I understand engines, but need a little clarification on how...

Need some opinions on choices with intake manifold. Not sure I should have posted in this thread or in the fuel section but I looked for other intake questions and most seemed to be posted here. First let me tell you what my combo is with out the intake. I am building this in a 66 Dart. I have...

When I bought my 66 Dart it had a 273 2 barrel carb. I knew I wouldnt be keeping it so I sold it right away, then the question was what engine do I put in it. The engine shop owner/builder is a big block person. He had ready to go a stroked 400 but after doing some research on headers I decided...

I am looking for a Decent set of roller rockers for my 408 build. I've run into so many extra expenses so far so I would like to not buy top dollar rockers. With my luck I probably won't have a choice! I was looking at the mancini rockers and shafts. I always thought their stuff was good...

I have posted in a different thread about the lifter galley issues on my 92 or newer 360 Block casting number 53020006. My issue was the lifter (solid roller) (comp #828) coming up far enough that the block oiling hole inside the lifter bore was exposed just above the roller. Now its not an...

I have a 408 stroker that will be running a solid roller cam. I tried buying a Milodon Oil Pump Driveshafts 21535 assembly from both summit and jeggs only to find out that its back ordered until sometime in May or June. Of course the Mopar performance one is available for around $75 more. I...

I bought this block a few years back from a guy that didnt know what it came out of. Was wondering if anyone could help with year its from. I think its a roller block which makes me wonder why I am running into issues with the lifters coming up past the galley holes, but I want to find out for...

Ive read many posts here and still havent been able to find a definite answer to what I see as an issue I am running into on my 360/408 stroker build in regards to the Comp Solid roller cam. I am using a .575 lift both intake and exhaust. the builder called yesterday and said we might have an...

Has anyone found a windage tray that fits a 360 striker or just use a baffled pan? Rodney

Can anyone tell me what the flow numbers are on a set of 915 J heads that have the large valves. What can they flow with some port work? Exactly what do they do to port heads? Thanks Rod

First let me apologize for this thread if it gets to long. But I need your thoughts to help me make a decision. I am building (having built) a 360 stroked to a 408. My plans are to drive this on the street about 1000-1500 miles a year to local shows and to take 2 trips a year to shows that are...
