Purchased their 1150 Dominator for my 512ci stroker & looks great. Can't tell it from new except for "FR" stamped on top flange. Very happy.

I see my error, correct ID# is 2809401. 4101535 is the VIN. Sorry, I didn't mean to hijack this thread but you have solved a pretzel in my head. Tks all, great forum

I get it with no problem but it skips over my ID #'s I have a clearly marked case #J28 9401 4101535 Could this be a special application or motorhome unit?

Tks for your replies guys. As I said, many engines built over the yrs with both rope & rubber seals without problems. As ply65 said I usually only put a small dab on ends of seal but must have been overindulging that nite or simply distracted to put that much sealant in there. At least it...

Never had a problem with rear main seal leaks until new 512ci stroker build. Everything went per "text book" during break-in except minor but anoying oil leaks. Cometics valve cover gaskets solved half the problem but two tries at rear seal area didn't help. Finally decided to bite the bullet...

Too old to quit now

Looking for set of BB headers for my run-in stand. The 512ci stroker is nearing completion but I have no vehicle in mind yet so trying to avoid buying a new set that would not be usable in future. I've welded all my life so capable of salvaging smashed or broken tubes. Would prefer a decent set...

I've always used the March aluminum pulleys top & bottom on a MP water pump with both left & right outlet housings from 440source. March may be a little spendy for some but worth every penny especially when the uppers come with special button head allen screws for pump mounting that allow the...

I just purchased MEL-66-S5 from Summit for my 170ci & fits perfect, when you get the crank in correct position during installation. Hi

I'm happy with my 512ci stroker with right hand lower hose but timing is difficult with shroud unless you fab a left side tab.

This "big cube" (507) is still in assembly rack. No vehicle yet. Head looks excellent after repair. Really pays off having a senior machinist that knows the process. Need a few more items to button this one up. Getting close. My non-precision cc procedure is using a large syringe, not a burette...

Going electric has never solved a temp problem for me. Proper pulley ration & correct fan has always been sufficient. Good luck.

Trying to top off my 440source -512ci (507") stroker with a TM-7 intake. Saw a few on $leez-bay but thought I'd check here first. Prefer uncut but heads have been shaved so expect I'll have to do some work to make things right. Not ready to consider another brand/style yet, as I'm happy w/ TM-6...

My machinist is trying the seat replacement first. The 3462346 castings came in two sizes, 79.5cc & 81.5cc, however you can reduce the volume even more with flat valves rather than tulip but with a weight penalty. My reference to "small chamber" may have been misleading. Nothing compares to the...

Short block is done. Heads are done, well I thought so. Cleaned, maged, ported, gasket matched, polished, hard exhaust seats, milled to cleanup, paint, & freeze plugs. While lapping valves I found small dot in #2 intake seat so back to machinist (I do most my work). Each time we touched it, it...

Wow! First time I have heard that. I cut may templates on the lines and carefully sanded the line away just to ensure they weren't too large. Way back then I felt it better to go with slightly less flow rather than trash a set of heads. I can see if you don't orientate them carefully you could...

As far as this thread goes, it's all good input & I appreciate it. My first rebuild was a Lawson 1cyl ditch pump at age of 13. A "take home" from the oil fields in Long Beach, Ca. After numerous flat head port & relieve jobs I started enhancing Mopars & discovered the power of a Hemi. 60yrs...

re:YR Thanks for confirming my thoughts on both subjects. Time to get busy.

re:ir3333 No specific reason other than I still have two 72' (eastern) 400ci blocks w/under .030 wear but have already done that a couple of times. The 440ci has been patiently waiting for my attention while I watched the kit cost go up more than $500. The 512ci kit is most reasonable without...

re:IQ52 If I could get anywhere near 600hp with this combo I will be elated, over 700hp would be only a dream. re:roccodart440 I've considered the Comp version @ .509, 284/284, 114LC due to availability & complete package price. I've never used their products but heard good & bad. Calculations...

As I said "it's what I got" & I'll let the next owner do the upgrades ie- aluminum heads, FITEC, MPI. Sorry to hear of your bad luck w/purple sticks, I've used them on all my SB, B, RB builds except the slanty without problems. Although, admittedly, most were years ago and quality has taken a...

We were active competitors from 64' thru 69' as Perkins & Sons Racing. We were members of Gear Grinders with turbocharged 170ci slanty in Blown Coupe & Sedan & I was also member of Rod Riders in 68' with baby hemi in Blown Fuel Coupe. Yeah, 200mph with less than 300ci is a daunting task w/...

I appreciate the input from all. This is an "old school" build using a 78' motorhome 440 I've had in storage for 25yrs. Finally getting started after two other stroker builds, first one was a Speed-O-motive 451ci done 22yrs ago. Sticking with iron except for TM-7 intake, Dart adapter, & 1050cfm...

Thanks for input. Decision was made long ago. My racing days are long gone. This is a "Coffee Cruiser" & I probably should have said that originally. My question still "is there a benefit to the additional flow holes along the bottom edge of the late head". I expect both sets can be made to...

sorry, missed the pic

Ordered my 440-512-5075 kit today. Need to make decision on heads. Early 70's 3462346 casting (right in pic) will need new guides installed or Late 78' 4006452 casting (left in pic) will need hardened exhaust seats installed. Both have 81.5cc chambers & will be ported using DC P4120437 plastic...

170ci rod is 5.669 198ci is 7.006 225ci is 6.699 Would be tough to combo one even with offset ground crank.

Over 4yrs ago I said I'd give an update to my heat concerns. Well here it is. Parked the car, except for occasional coffee runs, and started on my 451 stroker. Revived it this week, built a shroud, removed all electric fans & controls (what a waste of $$), installed direct OEM 6 blade fan and...
