Hi all,
I'm opening this thread, to get some tips, tricks, suggestions and confirmation that i'm doing a good job
To start off i'm going to tel some history about my last engine that is wrecked. When i build the wrecked performer engine(2800 to 6200rpm purple cam) the car was a 4 speed manual shift and it was a great performer and driver!! Due off my ex-wife wasn't able to drive the car with the manual trans.... We converted it to an autotrans This was an bed idea, i know now. From the moment we did the conversion al kind of troubles started and the engine didn't perform like it used to. I never thought the problems came from the trannie conversion... Didn't even tought about it :banghead: stupid me!! The engine was build for an manual shift and not autotrans. I drove the car for another 4000mls with the autotrans, abusing the engine to make it perform like before... Never did by the way!! And then it happend... doing 70mph on the freeway... a lot of noise under the hood!! We towed the car to our shop and started to investigate the problem...
The bearings on my rods turned over each other and wrecked my crankshaft and one of the rods. ops:
The last engine did only hold up for 8000miles... the new engine should hold up much longer i hope?!
I bought myself another engine, A low mileage '78 360 with all standard bores!! I'm going to use the top end of my old engine. The heads and intake worked great before and are great combo!:cheers:
The Duster is equipped with an 904 autotransmission with shiftkit and a 2400/2600 stall convertor behind that is a 8 3/4 rear axle equipped with 3.23 posi gearing and a tire height off 27".
I already sorted out some parts for my build and some parts i still am figuring out. This weekend i'm going to cc my heads to determ what static compression i'm going to have.
The heads from my old engine that i'm going to use are in good shape. They have been port matched to my intake(weiand accelerator) and exhaust headers. We smoothed out the intake and exhaust runners and get the good valve set up in the heads(1.60 and 2.02 valves). I'm using the standard stamped steel(MP) valve train with(MP)springs because i don't have the budget for an aftermarket rocker kit wright now!! But i think when i'm not getting to crazy with my cam choice those wil be ok?
I'm not looking to get the max power out of it but i must perform enough to do a sprint down the strip ;)
After cc-ing my heads this weekend i'm ready to do the math and ready to determ what parts i'm going to order.
The parts i sorted out sofar(not ordered yet)
8 Sealed Power Pistons (Hypereutectic w/ 2 valve reliefs -5cc)
Dana Rings (moly)
Cloyes timing set (dbbl roller)
Clevite main bearings
Clevite rod bearings
Clevite cam bearings
Melling high volume oil pump
Melling pick up tube
New freeze plugs (Brass)
FelPro full gasket set
The questions i have for now are...
What is the max lift but safe lift that the stamped steel rockers can take without breaking??
am i forgetting thing in my parts list?
For now.. enough typing.
looking forward to the reply's
