I have a 400 2-bolt ready to be built into 406 (.030 over) for a modified car. I need good suggestions on what is the best (reliable and fairly priced) parts internally. Will be running alky and prefer high compression (13:1). Will be using Dart Iron Eagle heads 64cc (comp. springs, etc.)Victor Jr. intake with 750cfm 4-barrell carb. HEI distributor. Trying to keep cost fair but reliable motor.
Crank? Pistons? Rods? Cam (currently use Crower #351 cam)?

I'm by no means an expert but I would think with this kind of comp. I would run forged pistons a forged crank andI prefer oliver rods though there are a lot of good ones I would watch for good used parts from places you know are reputable I buy a lot of parts from an ARCA engine builder and have bought them from some folks that built lat model motors and at the end of the year there were a lot of good parts that the big guys didn't want to use but worked fine for me I assume that being a mod you will have to consider the claim rule which really would have a bearing on the parts used (at least it would for me}

if it were me personaly i'd run a scat internally balanced crank, 4340 scat i beams, and wiseco pro tru pistons. that should be around 1100-1200$. after that i'd get it all balanced up!

I would not run that much compression without putting in billet splayed main caps.
Even then I would worry about it in a stock 400 block. my 2 pennys

A good bullet proof assembly , that wont break the bank , would be a Callies Dragon Slayer crank , Crower Sportsman rod's , and SRP piston's .

CNC DOC hit the nail on the head about the stock 400 block . Aftermarket main caps are a must have . Keep a good eye on your second main web , eventually it will crack .

Also , do your self a favor and spend a few extra dollar's on the 2925 Super Victor . It is a much better intake that the V/JR ! If you still want the V/JR , be sure to use at least a 1" open spacer on it , but preferably a 2" open spacer . The V/JR has poor fuel distribution to #5 and #7 without a spacer .

Steve,

Hadnt seen you on here in awhile.

I have quick ???

I recently got a mail order catalog that had a Callied DragonSlayer with 400 mains and 3.75 stroke. Previously these were not available.

Are they now available and easy to get??

Thanks
Jim

Hey Jim ,

Yes , they are now available . As far as easy to get , I'd have to call Callies and ask . They are moving a lot of these crank's , so they might be a little behind . But usually they have plenty in stock .

Steve

P.S. Yes it's been a while ! I've been very busy with our business , got married , and have not had much spare time .
