Now try it with a 4.15 crank and 11.0 comp... Then add OOTB Eddys and a little more cam... Then add MCH Eddys and a little more cam... Then add maybe a Victor jr. and 2" headers... thanks

I often have more fun doing a budget build than a build where cost isnt much of an issue. Thanks for sharing the results.

So, given a choice, adding some roller rockers would BE the 1st money you'd spend additionally? The HS Mancini's, for example? S/F....Ken M

I would ask that question as adding an adjustable rocker or the correct length pushrods.

Being a budget build, what about some cast steel rockers? Cheaper, will work with a lot of cams, including mild rollers.
I have often considered a 400 stock stroke motor to have some advantages as a bracket motor as well as a cheap street combo with good potential. Lower torque off the line would really make consistency easier to achieve. A juice cam and pump gas equals cheap, many runs before maintenance racing!

My take would be
same crank and 13:1 pistons
then add 325 440-1s
then add 275/282 roller cam
then add 1050 pro sys dommy
then add another one.

It started getting a bit rich in the top end looking at the A/F and BSFC, there could of been a little more power there.
I think because of the non adjustable rockers, and having about .050 depression on the lifter plunger, we were seeing some lifter pump up causing erratic #'s.
For sure, with different rockers power could go up a fair amount. I thought the TQ curve was pretty good as well as the wide powerband for such a short stroke.
I agree,the heavy stock sized valves tend to keep a hydraulic cam from working well at higher rpm's unless everything is just right.
As for leaning it out on the top end for more power,that does not always work out so well. I have spent a lot of time getting a flat A/F across the board before just to find that the engine wanted the extra fuel. It depends on the fuel used and how the engine combo is working with it.
I have also tried it at the track to see how the results from the dyno pan out. I have had to go back to the richer settings on the top end to get the mph back up. Many variables come into play!

I was looking for a budget oriented strong street/strip combo that makes about 650 hp in a stock block. Plus, I have a 4 speed tranny, so I'm kind of limited.
I'm not rich like you guys with your roller cams and high-dollar heads...
Then, when Brian is done building and testing it I can buy it from him at a discount.
Quit wasting your money on 500" big blocks and you can buy good heads too!

Ha ha! You guys crack me up!!
650HP and budget should not be in the same sentence IMO.
Yeah, the 400 is for sale...even if it's not 650HP!
Brian, how do you think this combo would stack up for cheap HP?
406 cubes, hogged out iron heads using the old MP templates, flat tappet mm305 cam, tunnelram with two Thermoquads (by Dave, AKA Quickd100). Won't get much cheaper than that for an all out hp "cheap" build! If the shortblock is built right and the heads flow about 270, should be able to make 600+ anyway.

I don't know about dyno numbers, but I can chime in with one of my 383 experiences...low dollars and NO SENSE, lemme tell ya! Using 100% used parts, except for rings, bearings, and oil I slapped this together:
*Domed TRW slugs, didn't measure actual CR, but it was zero decked with a measured 80 cc 452 head.
*Resized stock rods with good bolts.
*Those 452 heads went 250-ish on our bench.
*MP 590 cam
*MP single plane and 3310 Holley
*8" converter
*4.89 gears w/a 29.5 slick
*Weight 3420 E-Body
*10.90 @ 122 in real good air
Same motor, heads improved by 15 peak CFM...
*Ultradyne .613/276 @ .050 cam
*Adaptor and 1050 Dominator
*A body at 3180
10.62 @ 125 in Sacto summer air
Then added a TR and twin 1406 (?) Eddy's, more tweaking and got it to go 10.43 @ 126 best. Yes, most all said "it just had" to be a low deck stroker. Those little 383/400/406 wedgies CAN run!
