someone on here was selling their 360-1 head small block that made in the 700s and said it was a $19k engine.
So I will guess 26k

So I will guess 26k To get a REAL 900hp from a true inline wedge smallblock.......26K won't begin to touch it, even if you can do it, which I have my doubts. I know guys can produce dyno sheets that SAY their inline motor makes that, but that's another discussion. That power number can be attained with canted valve heads, but it's still likely going to be a 40K small block

Do you consider a gen III a SB? The engine masters make 700 with them and they have RPM limits and cams are basically mandated by rules to be on the very short side of duration as well as very conservative compression limits. Throw in 30 degrees more cam, 2 points more compression another 20-30 cubes sheetmetal intake more liberal port size and I think it could be done but like Monte said you may get it on a dyno but in the real world who knows till you try it.
If inline wedge is it than a W8 is the only way to stand a chance.

Im pretty much guessing here but... R5p7 with more comp, more cam, better intake should be close. Cost COULD be under 15k if you find a good used motor witch ive seen from $3500.

I know what it cost to build a 590 hp small block,,, more than I ever spent in my life on a motor,, as far as Brians motor, I am going to guess 55-60 g's.

IMO, the only "fair" way to estimate the cost is if you assume it was built from all new, currently available parts. Otherwise it's just a game of who can find the best deal on the best used parts, which not everyone is going to be able to come up with.
A 572ci BB, using premium internals and valve train components would be in the mid-20's.

An " upgraded" r5 p7 will be the cheapest way. I know a freshened complete motor can be had for 10k or less complete that will make 750-800 horse. It's then a matter of whatever is involved to make the extra power. Buddy of mine bought such a motor, put it in a 3000 pound car and ran 9.40's at 143 with it exactly how he bought it( for well under 10k complete) This was 12 to1 and had a dinky248/258@ 50 camshaft in it. Lots of room there to upgrade I would think. He took the heads off and had them flowed by a well known in these parts head guru and they went over 400. He ran a 4150 carb and old W2 headers he made work on it.

If you read the internet and listen to guys at the track...........there is a swinging dick on EVERY street corner with an inline valve, wedge smallblock, that makes over 900HP. I have been doing this stuff for a LONG time and have NEVER seen one, be it a Ford, Mopar or Chevy. As I said, you can do it with some canted valve stuff, but it's still not REAL easy and will be at a min of 40K if you do it with all new stuff.
I have done several 434ish Chevys and Fords, with the BEST 15-18* heads you can buy. A good one will make between 840 and 880, depending on cam, compression, rotating weight, etc. I have yet to see a Mopar head that was BETTER than the best off brand, so I am going to say it can't even realistically be done with an inline head........regardless to what some dyno sheets may say to the contrary

And as I said, if his does in fact make 850, that is a realistic number for a "killer" inline headed motor, because I see a LOT of those. a TRUE 900.....NEVER seen one. When you get to this HP level on this type motor, 10 hp is a TON, 50 is an eternity

Well I know what the 900-1000hp INLINE SB Comp stuff costs and they are generally well north of $50K. But these are small cube high reving deals.
For those saying I know about this or that combo making 700hp, who cares. 700HP is MILES away from a TRUE 900hp deal, especially in a SB.
Aussie Pro stock aint an inline head and the R&D money in those is STUPID money. I have around many very good comp teams and know what they spend on engine development and engine combos. Spend a fair amount of time at a builder that does Aussie Pro Stock P5 stuff and the heads up car we are involved with is basically an Aussi Pro Stock SB Chevy combo making 1055hp. So I have a pretty good idea what it takes and truct me you aint taking a 700HP combo and getting there.
