BOSS 5.0 iron block?

[SSeatr]

anyone build one of these yet?

i just saw on latemodelresto they are selling the block for $999

96-04 Mustang Boss 5.0L Engine Block, Cast Iron by Ford Racing at LRS - Same Day Shipping!

everyone else wants $1300++

MMR is crazy looking for $1699

but i think this is going to be the base for my next build, just interested in hearing anyone that has built one and how the power was.

as we know the 4.6's the stroke was fine just the bore was small so im excited to build one, instead of resleeving a 4.6 which could be nothing but problems and cost WAY much more then $1000.

+1 Tousley will have the best price for this block. With this block you achieve 323 ci with a stroker crank.

OP is your goal n/a power or are you planning on FI? If staying n/a then resleeving an aluminum block would be a better idea IMO because of the weight saving, even though it will be more expensive than the iron block. If FI is in the future build plan then the iron would be the direction I would go. That Boss block can handle 1000+hp.

Just finished mine dropping in the car next week!!! The boss block is a bad peice, when i had it at the machine shop we had it next to a factory 04 cobra block, and there are so many differences its not even funny, My machinest was like "DAMN" this thing is a really nice block, and has a lot of nice features.

We have the 3.700 bore Manley pistons in most compression ratios in stock, they are $699 and include tool steel pins, they are much nicer than the Diamond brand (the diamond brand uses a very thin skirt that is prone to colapse and make alot of piston noise, the Manley uses a thicker skirt and and it is full banded (means it is supported 360 degrees) we also keep in stock the complete stroker kits, with the 3.700 bore piston option they are $2299 and include everything but the block!

Please let us know how we can help!

i'am debation on stroking it right now. i could save some $$ buy using my crank and getting the rods resized along with ARP 2000 bolts
i would just need pistons and rings / brgs.

to stroke it ,

A stock stroke crank cannot be used in a stroker application, the crankshaft is the part that actually makes it a stroker, the pistons and rods are just along for the ride.

Most Stroker kits (at least the nice american made kits like we sell) use a specific rod and piston (different compression height and rod journal size) that is not compatible with stock cranks.

Hope this info helps a little.

The crank is by Kellogg which is far stronger than stock due to the oil hole drilling and MMR rates it up to 1500RWHP.

The crown thickness varies with dish but minimum is .120"

Most compression ratios are available, raising the compression .5 will aid in power but will reduce detonation resistance (always a tradeoff)

Oil support rings are a VERY POOR design and none of the strokers MMR sells include them, MMR stroker oil rings are supported 360 degrees by the piston, a support ring is if the piston pin intersects the oil ring and provides support in such a case.

The rods and pistons are Manley (not to be confused with Mahle) and include total seal rings and ARP hardware, ARP 2000 bolts are a $99 option and are required for 8000+ RPM but have nothing to do with HP that the rods support (under the power stroke there is little pressure on the rod bolt)

Assemblies that MMR sells are available both Digitally balanced like our shortblocks or unbalanced.

Our $1699 price includes machine work, keep in mind these blocks come un-machined from ford! The other prices you have posted are unmachined.

Just wanted to clarify :beer:

Why do you sell diamond pistons as an option if they are prone to collapse?

They are great for the non strokers and 5.4's but not the strokers, we offer them primarily because our customers like having the other choice.
