Going buy prices around here,it,s a 2-300$ job with no bearing,and a nother 125$+ for bearings,mrmopartech

It will raise the compression about a half a piont,so if you had 9.5:1 it would bring it up to 10.0:1,mrmopartech 450 424 0445

A very good double roller chain and gear set is all you need for a life time of performance,mrmopartech

The one you need is a 2536945 for 361/383/440 A body,the other is a hemi bell housing,mrmopartech

Rani,use this chart to check all the distributors,mrmopartech Either one can be used,the one on the left is the best of the two,have it re curved and set gap,and bushings checked and your good to go,mrmopartech

can you tell every one what cam was installed and the heads and springs you gave to install the cam,as some thing does not sound right,was it a solid or hydraulic, size and why you could not do it,mrmopartech

Give me a call,I sent you my number,mrmopartech

There is nothing wrong with a set of well done stock rods that have been lighten and balanced and bushed with new bolts.For decades,stock and super stock cars ran stock rods at high rpm and lived.If you intend to run over 6500rpm for long periods,go with the aftermarket,but if it,s a daily...

From years of doing engines,the piston to deck spec is normally in the .025-.050 on the performance 383 engines,the lower the compression of the stock motor,the more piston to deck height increases,as the pin center line to piston crown decreases,mrmopartech

Don,t do it,use the stock size and have a real head man do the heads and they will perform better than going to big valves,unless you have a 500+ cube motor,Mrmopartech

If this is a stock to mild build up/upgrade,get a dual plane intake and a 750 carb,and a good distributor and a lean burn electronic plate and a set of distributor springs,and with a good dual exhaust,you will be fine ,mrmopartech 450 424 0445

Moper,mark this day in history,as I agree with you a 110%,mrmopartech

You can mill the heads .020 and use the steel shim head gaslets and you will be fine.You will need to rejet the carb and re-adjust the timing and make sure you have adjustable rockers,mrmopartech

Your going to need a rebore all the cylinders and new pistons,as the 72 and later pistons are low compression units and you need a to make a good 10.5-11.0:1 to be happy,mrmopartech

The chevy pin is lighter than the stock pin,making a light assembly.Overall weight is reduced,which means HP.mrmopartech

There are a number of places selling the rods that can handle up too 900+HP.Just google mopar 440 connecting rods and about a dozen companies making rods.Price range is from 425-600 and some more if you want the top of the line.Manley,K1,Scat,eagle,are just a few,and order the the .990 chevy pin...

You are in luck,you can use the 383 flywheel on the 440 cast crank motor,BUT,you need to re-drill the flywheel to counter balance the unit for the cast crank.Now you ask your self,well how do I do that,and where do I drill it.There are 2-3 holes to be drilled from the spec sheet and needs to be...

http://www.wallaceracing.com/cid.php After doing your math on this,if you still do not get it,call the people at :Home& garden TV. [email protected]=4.372x3.750=450.37 they call it a 451/452 motor [email protected]=4.402x3.750=456.58 (457) [email protected]=4.432x3.750=462.82 (463) [email protected]=4.442x3.750=464.91 (465)...

I agree stroker,it,s 456.and some change which does not matter,the problem is if thet put some number in as the last digit, 456.574,or a added digit in the bore number or stroke.But the bottom line is,the other guys better learn some math and read some automotive math books,mrmopartech

We will assume its going over by .030,so its a .030 over 440 piston or a stock 400 unit.You want to build a flat top motor and have it deck to zero deck height,and adjust compression with heads gasket thickness.The KB pistons or ICON pistons are a good choice.With the icon pistons,you can get a...

First buy a used intake and have a machine shop drill and weld in the plugs,its cheaper,mrmopartech

I would start with 15 initial and 38 total and adjust from there,mrmopartech

2946728 is a 68-69 LH side 383 4 barrel exhaust manifold for a A body car,mrmopartech

Lower compression can handle more timing,40-45 degrees depending on cylinder condition,and lower fuel grades would help,to a point.As long as the motor is tuned and fueled correctly,it should run great on regular fuel.Each car is different,and tuning is a big key to making it run 100%.Running 93...

The only way for that to happen is the head has to be a closed chamber version to increase the compression as the old head on the motor was a open chamber unit,mrmopartech

The 2402557 head is a 1 year only head from 1963.It was used on the 413 & the chrysler 300J motors.Its a small exhaust valve head,as its a medium size valve at 1.74& a intake valve of 2.08.You need to post if its a removalble pedastile type head or if its a solid mount type.And if its still a...

Can you bore out a 413 .060 to a 383 spec,YES,is it the brightest thing to do with out sonic testing and scraping a great block,NO.If you want the look,just get a 400 block and a 440 crank and do a stroker motor.You can sell or keep the 413 and get great money for it.The 413 motor has a problem...
