Long overdue update!

I've been plugging away at the motor, bottom end is assembled and we're getting on the top end soon... cant wait!

Both stock and ported eddy's were CC'd ( intake, exhaust, & chambers ) before we flowed them


Also got the crank balanced - we needed almost 170 grams off both sides and instead of drilling the hell out of the crank we milled off the weight. There are a bunch of ways to get this done but this is a better result then the drill at that amount.



You can see this SBF was drilled to death - not the most professional way to get it done.



With assembly right around the corner I whittled away at the oil pump and passages - the filter area and rear cap took the most work - here is a progress shot.



With everything clean we file fit the rings... getting there!



HOME SWEET HOME!!!

500hp? please honestly you should see 560ish or more..and lots of tq..10's easy

All washed and ready for assembly!



Got the pins & rings on - the pistons have wire locks - man i go them down by piston number 8 - lol




A little lube on the threads and bottom of the heads to achieve accurate torque



Sinking the pistons in and the chamfer goes to the crank side. you can also see the radius on the crank and the narrow bearing that misses the crank.



ARP's ring compressor made dropping the pistons in a breeze - it's tall enough to get the rings set in it at the bench and then drop it right in at the block with your thumbs.



A couple feeler gauges set in between the rods keep everything square and true while torquing.



The 4.125" stroke and 2.00 inch rod journal make plenty of room where a stock mopar diameter rod would be into the pickup tube. I'd be curious of the 4.250 stroke in this area


Before checking the pan to pickup clearance - please look over and clean your pan - any weld spatter or dirt will get right into the engine.. ours had weld spatter, and took a bit to get it cleaned and free of these little buggers -

Should be on the dyno this week with a mild configuration

any guesses?
430 cubes
stock eddy heads
air gap intake
Comp XR286R

LS 110

Intake
Duration @ .050" Lift: 248
Valve Lift: .576

Exhaust
Duration @ .050" Lift: 254
Valve Lift: .582


I have a couple carbs to try out - 750 ultra hp, 830, 950 hp and 1000 hp... still undecided.

Earlier in this post I thought you said you were going to use ported heads with 2.05 valves.

Yeah I thought the stock eddy heads were only good to 475ish? Are they ootb or did you clean up the valve job?

I run that same cam in my 410 stroker. I bet you get ~ 530 hp with a pile-O torque.

when do you think you will have it on the dyno? cant wait!

My guess is gonna top out at 475hp and make ALOT of torque. Horsepower and torque are gonna be a very flat curve.
Max port those eddies and I see 575 very easily.

I would love to take a guess, but you know what numbers I'm really interested in. I expect you to give us the full report.

Watch closely boys and girls.A lot to be learned here.Dave you have done one outstanding job and have taking a lot of time to show us all how to go about doing an engine the right way.I would really like to thank you for the pictures and the attention to detail you have put into this build.I would say with %100 certainty that your dyno #s will teach us all a lot on how to go about making power and what it takes to do it.Again thank you for the time you put into this and for sharing it with all of us.

Thanks for the compliment Hitman - I'm not expecting a ton of HP out of this combo, as the heads are bone stock.

I did blueprint them and had to open up the tight guides, as well as correct a few intake valves that had some stem runout. but aside from the springs, etc to match the cam they are stock castings.

There will be several variations of the engine on the dyno and I cant wait to hear this sucker run!

fonse!! outta all the times i looked at ur post i never realized(good place to do buisness)now if the heads are otb 100 stock your still gonna make well in the 500's but if there done by rj i'd say 575ish with 550ish atleast tq...which means mid 10 sec cruiser good luck brother.

These were STOCK heads - not OOB since I had a few tight guides, and a few intakes that the seats were 1.5 thou oor - but aside from that and matching springs etc they are stock castings, not even decked.

I ran 2 carbs today -
the Ultra HP 750 & the 830 Annular

and they were withing a hp or two - so the carb is definitely not holding the engine back - the heads are at this point....

all I can say is WHAT A TORQUE MONSTER!!!

Any more guesses before I spill the numbers?

Spil em!!! My guess 463hp 589 tq

480 hp./557 tq.
