Yep, the 84cc version out of the box. Short block has been together since the early 90's.

Only had it to the track once so far and i was shifting at 6,200 and it felt like it was still pulling. I am running the stock springs that came with the Edelbrocks. The specs are close to what Lunati recommends. They told me i would be fine using those springs.

I have that cam in my 383, recommended by Lunati. .030 over, stock crank, rods, old trw flat tops, eddy heads, street dominator intake, 4.10's and at the time an old fairbanks 2,400 stall. Dart went 12.80's with a bad bog in the carb.

I would say you have more power in that combo. I have a 383, .030 over with trw flat tops, no valve reliefs around .020 in the hole. Using stock 516 heads with the small valves, holley street dominator intake, holley 750 double pumper and the mopar 284/484 cam installed straight up. With this...

That's not good.

Really good information here.

More opinions than i thought there would be.

Thanks for the replies. A few different thoughts on this topic. The motor is not apart yet, it's down to the short block at the moment but it will be coming apart. At the very least it will go to the machine shop to get cleaned. At most it will get cleaned, decked and honed. Either way i...

When going from bolts to studs in the main's, is it necessary to have the main's align honed?

I am trying to do this build on a budget. This all started with me just pulling the 383 out of the dart to check it out and my main goal was to buy a set of heads shortly but i want this thing to be faster than the 13 second passes it has been running. I figured it is apart, why not see what...

These prices aren't that bad. I will have to get on the phone shortly and see what i can get it done for in my area. Thanks.

What would be a rough estimate for the machine work to put a 440 crank into a 383 block? Mains cut down and counter weights cut. I am trying to get some ideas cause there aren't many shops in my area and i am not sure what kind of prices i am going to get when i contact them. Thanks for any...

Ok thanks. Just wanted to make sure i didn't have anything funny going on.

Stock big block rockers, how much side to side play should there be?

Motor is a 383 and i had the oil pan off of the car. I did not build this motor but if i look up to the bottom of the pistons i can see the numbers 233-99. Does anyone have any info on these pistons? Really curious if they are cast or forged.
