This whole thread is nutz. Guys saying they can build 900 with w8-w9's all day long, really. I don't know if you guys pay attention but many of these dyno champs do not even run 150 in a 3000 lb car on good days. A 900 HP build should trip 150 in the worst air. On a good day should run close to 158. If it doesn't either you have a car problem or a dyno operated that is doing something wrong. If same guy built it and took your money he needs a bruised eye.

If you know where the deals are and have some luck you could build for $10k. I did it once with my 457cid in 2000 with 100% American parts. Shops wanted $35,000 to $60,000.

I paid 2400 for machine work done on a virgin block from Charlie Westin cam tunnel 60 mm w berrings,lifter bores bushed,bored,honed,decked.
Holy shishkabob 9600 for block work on a 600 dollar block.

Sorry, I simply don't believe it makes that much.

AndyF.........the only reason I mentioned an inline head was the price range some were throwing around, an inline was the only thing to be in the neighborhood on cost. If you are not used to building high HP motors and you know the motor that you have that makes 700hp costs X amount of dollars......it is hard for most to fathom that 200 more hp will likely triple the budget at least. I mean......it's ONLY 200hp more.........right, how tough can that be.......LOL!!!

I didn't bring Comp motors, Aussie Pro-Stock and that type stuff into the conversation, because that stuff is in another world

You don't believe it because you don't know how to do it. I know what I have and the et is the proof. It can all be verified. My car is well documented.

Here is what I said for those that missed it...........and several of the posts were directed at Ray or others directly.........as the thread had drifted from the original question, which indeed had NO restrictions on combination...........If some of the commenters had indeed read EVERY post, they would have known exactly what I was trying to say............but that is not how it works around here. Read ONE post and get in where you feel you can take a shot at somebody is how it works here.

I KNOW what Leopolds engine made. Was just involved in the sale of another AS car that was that came with 3 engines. The best of which was about 30HP behind Leopolds P5 deal. Yes I said P5, as that is what Leopold runs. His old W8 stuff was good too and now resides out west here as well. That is NOT a cheap motor at all and IMO not sure why or how a P5 is allowed in SS, just saying....

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

Is this Richard Kay, if so, been a fan for a long time. Love your SS/BM Valiant.

shouldn't we be asking why you would want a 900hp N/A engine, instead of how much it would cost?

off subject but.... Rich, good seeing you at the Dutch , how far did you go in eliminations? I know you won first round... and Jimi the AA/SA Belvidere is awesome, is that really the former BA car?
