Many big block components "fit", as I recall. A custom crank is needed to use the BBC timing set. There's probably some sort of sleeve assembly to make it work if not a "blown" application.

So, if you're looking for the least expensive way to make "big" power and "live", Rocket is probably not for you. If you want the ULTIMATE in SBC technology and the most "bang", regardless of "buck", Rocket is the way to go.

Might want to gert your facts straight the Little-m is not a replacement for the 400 block.

The Dart SHP block is more of a replacement for the 400 block.


Dart has there Iron Eagle block which is a replacement for the Rocket block with and can be bought with a STD. or BBC cam tunnel, 4.00 or 4.125 bore, 9.025 or 9.325 decks, 350 or 400 mains.

Yepper-it's in the provided link I posted.

thanks for the info guys its really apreciated, i wasnt totally aware of how exspensive it would be to fill the rocket block, so im going to look into the iron eagle instead.
im thinking 4.125 bore 400 mains standard cam tunnel std deck as i can still make it a 434

ill prolly still buy the rocket block and let it sit like my friend has cause 2,200 seems like a really good price and im sure i could make my money back + some on it down the road

[Mr. P-Body]

Sorry. From my point of view (engine builder), Little M IS a "replacement". That is, all the correct holes and flats and knooks and crannies to "fit" where a stock block "was", are there. Agreed, SHP blocks are less expensive and more "amed" at the street crowd. I certainly didn't intend for that to be a "blanket" statement excluding all others.

I would go with the bigger cam tunnel even up to a 50MM rolller if you go to the 55MM roller get the IE with the DRCE oiling, Once you go to the bigger cams its best to go to a bigger lifter like .904 with an .810 to .820 wheel depending on the lifter suppier.

Thing is with options with these things is it is a slipper slope in costs.......

or just buy the tall deck and build a nice little 472 street motor.Tell everyone its a 383.

I depends on how reliable you want the valve train with .904 lifters bigger body, bigger wheel and bigger axel and with bigger base circle cams its always a big plus over standard lifters and standard journal cam.

At least that what I am seeing with shops and engines builders I supply blocks and rotators too.

wet sump
tall deck block
max displacement is 455ci
i can purchase this block for 2,200 bucks , how stong are these gm blocks

reason im asking is i am building a 434ci twin turbo small block to run in x275
it will be 434ci 9.5-1 cr, with cnc afr 227 heads, solid roller cam , single plane efi intake with twin 66mm turbos

this combo is capable of 1000hp plus easy

with this block handle it or should i just buy a little m

Closing up early today so I'll just leave you guys with this rocket story.

Well might I suggest if you suggest a option,quote him some pricing what it will cost.

Lifter bores machined for .904 llifters 250.00

Cam tunnel for 50MM roller cam bearings is 450.00

[1Gary]

Yes that is the machine work costs,but how about the lifters and cam needed??.

We went through this with two separate aftermarket BBC's.I'm not saying for him not to do this,rather I am saying once you step into the world of aftermarket blocks and their options there is whole other pricing structure which he should be aware of in advance.Easy from here(the "cheap seats") to advise what to get,but he is the guy who has to pay for them. Just my two cents worth.

If your buying a new block wouldn't you need cam and lifters any ways I guess you have some low end builds and some high end builds.

yeah but whats the cost differnece between the standard cam, cam with bbc bearings or the 50mm roller bearings and also the standard bore lifter versus the over sized lifter.
