ok what block? 11.7 or 12" deck height

looking to update and change some things around in one of my cars, right now im running a 665 n/a deal and hurt somethings, while im rebuilding this one was thinking of putting the together another motor. bigger, looking at a set of b441A/C heads or a set of thor 2, and thinking about doing either a 11.7 or 12" deck block, pros and cons of each? would i be better of with just going with the 12" block?

also as far as the heads go would i have to widen the car of i did go with the b441 heads?

What are you running now? Car, engine & heads?

car is a glass body 55' ford, motor is aluminum 10.320 block with tunnel ram & profiler heads but it ate number 2/3 chambers up and the pistons, went 7.10@191 heads need to be touched up and valve job. car was build to run local t/s and quick 8/16 stuff around here D1 stuff,

I'd depend on how big you make the engine. The 11.700" deal works good with ~ 5.00" stroke.

Hell you want to go real big might as well just shop around for a used mountain motor pro stock 820+

Run the combo you have with an 11.200" block.
If you decide to go with a 820" motor, you better do your homework with the maintenance that is needed. It may change your mind.

id love to have a mountain motor if it was well taken care of and not run into the ground. problem is some people want almost what they paid for new for the used stuff, i know its not cheap but still.

what's the biggest the 11.7 deck can handle, cubic inches wise, also whats a safe zone?

also could you get a 5.25 stroke in the 11.7 blocks or is 5" the safe zone,

and whats the limit on the 11.2 blocks?

buddy of mine has a 814 A441 motor for sale ,don't know how much but you could give him a call it's just been freshened call him and ask for Garth 403-7514 he went 5.4 turbo

I think you are missing some digits from that phone number Frank.   

An 814" motor with A441 heads is gonna be a dog.

If your going with a 5.25" stroke, an 11.700" block would be about right.
You could do a 12.000" block with that crank.
Did you talk to Carrol Carter?

403-793-7514

11.2 or 12" are the popular combinations
11.2" will accept up to 5.25 or so stroke
you can go to 5.3 or 5.5 stroke in the 12" block just fine, if you don't like the piston maintenance of the 820" combo.

There is quite a spread $$ wise, between new Thor heads or used B441 Hemi heads, but it is worth it.

If you think $35,000 for a used complete Ford hemi is "NEW PRICE", better think again.
Call up Carroll Carter and prepare for "sticker shock" on new complete B441 Hemi heads!

it had run 6.80's -6.90's in a 2350 lb 2001 mustang

Call Kaase up he's the godfather of the big fords. I'd be willing to be the will know where a few are for sale.

care to explain? are the "A"441 heads not big enough for 800" plus combos?

thats the thing though, 35k is not a bad price at all. the price i was giving to buy the one i first looked at was 65k and it still needed to be gone through. not a problem but at that price i rather spend the extra and just have a fresh new motor built. im not scared or worried about the maintenance either so thats not a problem.

I had a 5" bore space 827" Hemi with the "C" hemi heads, 2.75" intake valves. They flowed 655cfm; I also I had a 565" Hemi with the "B" heads that flow 550cfm. I don't think an "A" head will come close to that, maybe 450cfm. An 820" engine with "A" heads will be a dog. There are guys running 720" hemis with "A" heads and I think that is still to much displacement for those heads.

The guy I bought my 827 from was shifting it at 8600 rpms.

If you want to build a big inch 4.9 bore space engine, you need the "B" head. I think Carol get 18K for the heads complete. I just sold my 565 "B" head hemi last week.

thanks for clearing that up. also i take it the C hemi heads are 5.00 bore space motors only?

YES
