Why are you boring to the max on this build ? What happens if you need to fix something and bore again ??? I would only bore to the minimum required ... AFTER a sonic check ...

Here is email , I can't find his website . dan@performanceonlyracing.com He can get you anything you want including sending you a complete and ready to run engine .

It's not that the crank, rods or pistons are junk , the pistons are probably the nicest part of the kit , it's the finish machining that is suspect being the stuff is finished in China and you get what you pay for . Call this shop , Performance Only Racing Engines and Talk to Dan , he is near...

This is incorrect , you can build a 511" low deck using the same pistons as you would to build the 451 and the 470 ... 1.320 ... the difference is the rod used to go with the stroke . PRO470 , make sure you have the crank checked, unfortunately you'll be stuck with it since it will be cheaper...

I see they are a step head piston with a .095 dome , you need to pay close attention to the depths of the open part of the chamber across the entire head , they will not be the same chamber to chamber . with good uniform quench you could safely run 9.5 compression on 89 octane , maybe even 87 ...

Was this engine rebuilt in the past, is it overbore or has it been decked a ton , someone swap in a low compression 440 piston because there was a factory 400 built with a piston that high in the hole ...

This is the correct opinion , there is more to installing cam bearings than just banging them into place .

That's 5 total including the filter , it's a 4qt sump .

Yes you can use the register mounted pilot bushing/bearing , be prepared to trim the input shaft of the trans as the hole is probably not deep enough . you are going to need to have the flywheel balanced for external balance .

For every .010 cut off the deck surface you cut .0123 off the intake surface ,also be warned that the valley end rails would need to be cut that same .0123 , most don't do it and just force the valley gasket into place.

the 187 pan use a straight pic , the 402 a bent one .

Spare tire will be the same as what is on the other 4 wheels so if it would have fit on the narrower wheel they would have just used that wheel. Not sure if the bolt is longer , or if it needed to be , the one in the car fits fine with the F70 jambed in the well .

What was done to the heads , that's not a big cam but some think 550HP is easy to get from a stock stroke 383 , your combo shows it's not that easy . Unless that 452 is rear wheel HP

14x5.5 steel wheel , tire size I think was a D70x14 redline , goodyear me thinks , tire may have been as big as an E70 , but no bigger . I run F70's on my dart and they hit the frame before hitting the steering stops and the tire doesn't fit the sparewell INFLATED ...

What cam ,what INDY heads, and what is your compression ratio ?

Really , show me an easy 550HP 383 build please . :happy1:

i would be looking at adding an X pipe , you'll more than likely still have a drone wit hthe dynomax muffler . I'm dealing wit hthe same thing on my Dart , X pipe is the next try. I have a Dr. Gas I bought a long time ago so it's going to end up in my dart .

A body would use the shrotcase dynomax hemi turbo , I have 2.5's with mandrel pipes and factory big block A body exhaust manifolds and it has an awful drone .

I have a nice set of originals , no heat riser , for $200 plus the ride ...

Oil path is the same big block, small block and hemi , the mains are fed by the main galley , which runs thru the lifter bores and at the point where it feeds the mains it has a path to the cam bearings . it is a little louder than I remember for a comp XE but I just went thru it with stamped...

Good point on the valvecover but it appears to be tapping wihout the cover also . As far as the shaft impeding the flow , that won't happen . What happens is the rockers don't get oil to the high stress area where it needs it. It would be a good idea to pull the rockers and shaft and look for...

ahhh , no ...

First off Comp XE grinds are noisy . Oil path , pickup tube > oil pump > filter > passenger side main galley ... which feeds all the lifters > there is a path down to the main bearings > main bearing feed also feeds the cam bearings , #4 main feeds the #4 cam wihich hit and miss feeds the...

Yes you need to swap intake and exhaust on each pairing of rockers. The bolt is a short one , it's the same length on the top 4 nearest the valley and the row under the exhaust , but you can't just go to the hardware store and buy a bolt .

Yes they are on backwards , all of them , and you are missing at least one head bolt . rocker bolts are 25 ft/lb , heads are 70 ft/lb

What he said , and something looks odd , can you put a another picture taken a little further away ?

How thick a shim do you need ? I'm talking something like .010 between the rockers and the holddowns and your makeshift spacers . If you mean spacers RAS has spacers or you could make some yourself from some tube stock that fits over the shaft and put a thin shim between it and the rockers .

Junk is junk , I wouldn't trust those rockers , Cat rockers have the same issue , as far as I could throw them. The shafts are brittle and they care how far the valves are opening . there is a thread on DodgeCharger.com that I like to post up , Brandon cried to moparts about me posting the...

Nice work , when you get the iskys new the instruction sheets tells you to grind off the tabs , that is the only way to get them centered , it's not a problem with the crane versions as they are the proper width , I don't know why isky made them wider. On the galled rockers if they aren't bad...
