Oh wow a nailhead! Definitely no mistaking but I'm sure finding one wouldn't be easy. I like all GM V8s

Would anybody feel like running a dyno sim or desktop dyno on this (these) combo?
383 9.5:1 with 64cc heads (ZZ383 short block)
1 5/8 long tube headers
RPM Air Gap, 750 CFM carb, no spacer
E-Tec 170cc 60975 heads (64cc comb chamber)
With the following cams:

Howard's: (retro-fit cams but I'd ask for '86 up)
113215-08 217/225 .495 .500 108 LSA
110885-10 225/225 .525 .525 110 LSA

Lunati Voodoo (also retro-fit)
20120710 211/219 .507 .515 112 LSA
20120711 219/227 .515 .530 112 LSA
I'd like these on a 110 LSA but I don't know if you can just plug that in?

I'd like to use only 1.5 ratio rockers

Well..yes. I know a 383 will give me what I'm looking for, probably even a 350. Was originally looking for max torque from a 383 but you know of course the more cubes the better. If I only had one project car I'd invest more into a single build but I have to spread the spending. Not that a 400 can't be done for the same $ as a 383, I just don't know anything about steam holes and cam buttons.

let us all know what you finally decide.If you build a 400,get a good block,dont mess with steam holes.Like the 400/427 I told you about with new parts.I used a dart block for my engine for a few reasons,power/reliability/strength,all with room for a few rebuilds

.. Most important part for a 401... LOL!:

Offenhauser 360 Degree Dual Quad High-Rise Intake Manifolds 5692 - SummitRacing.com

.. All other 401 parts readily available...
____________________________________________

.. SBC 400 cheaper to build than a 383... don't even need to change the crank... 400 is a 383 with .095" overbore already done.. 406 is 383 with .125" overbore...
_____________________________________________

.. Buick 401/425 and SBC 400 include big torque at no extra cost...

.. SBC 400 steam holes no big deal, lay gasket on new heads (if used) and drill 1/8" hole where gasket indicates... only need to drill the 3 lower holes in each head, any steam or air bubbles where the upper holes would be just floats up and out the water jacket hole above it... as long as you don't drive the vehicle upside down... cam buttons for roller cams are the same (simple) problem for any size Gen. 1 SBC that didn't come stock with roller cam/provisions (pre-1986)...

For a simple drop in I'd like to get the motivation to start up the Olds 455 I have on the stand. I have the money but not the time and patience. But at the same time I'd like to assemble some parts myself.

Buzzlol: I know the use of a cam button fit a roller retro fit is required on all pre 86 Gen I blocks. Is that a set it and forget it type deal? Or will the end play change over time?

.. Cam buttons usually a permanent oil-lubed setup... your choice of nylon, aluminum, or ball-bearing button...

.. Your 4 383 combos look like 375 - 425 HP and 430 - 450 lb.-ft. depending on cam size...

Thanks Buzz. I first go the idea of a short duration high lift cam high torque 383 from the following forum post. The post by AUB72:

.. Here's a short duration (204/216), good HP, good torque, 'budget' 350 build... much less expensive parts could be substituted for some of the 'budget' parts it uses/tries to sell you... mainly relies on really good porting of stock heads and good quench...

I'm looking for a combination to give me lots of torque right off idle and a HP peak of around 5000-5500. The difference in what I will use would be 9.5:1 compression (ZZ383 shortblock), Edelbrock E-Tec 170cc heads, and a single pattern cam such as the above or maybe a Lunati 211/211 .507/.507 110 LSA (if they would grind that for me), and an RPM Air Gap manifold. I'm mostly interested in torque and getting to about 500TQ is my goal even if HP is only around 400. The only thing I'm dead set on is using the E-Tec 170cc heads.
With your combo if everything is perfectly tuned machined and assembled 450ftlb sounds about right.
