What does anyone think about this engine? http://www.ultrastreet.net/ultrastreet/472_675_engine.asp

Also would this fit under the 3 inch cowl hood being that it is a tall deck, and could this be twin turbo charged with such thin walls?

That's the same block that I'm using. It fits under the stock cowl hood no problem, but getting headers to fit is a challenge.

That's pretty cool they have a long block option for turbo and supercharged setups.Im curious did you get pricing on the long block or you looking at a complete setup?

[rocketman]

i have built acouple for some dirt late model guys here in town and have had no problems,both of them are running 15.1 comp.doesnt overheat and makes killer power.

15.1 comp would be about the same a twin turbo set-up.as far as cylinder pressure.

[Sales@Dutchboys]

thats a sweet motor.....

Cool thanks Scott. Yeah Johnny, I was looking for the whole engine. complete. I could not have 15.1 compression on a street engine, because California gas is not that good to support it, and I don't want it to be non pump friendly. I'm still weighing options for the near future.

Indeed. I wonder if that 2yr/24K mile warranty that they advertise applies to their long blocks as well as their complete engines? :D Now THAT would be pretty cool....Somehow I doubt it!

There not street motors,I was using the comparsion for comp to a TT set-up

I am thinking about building a 488 sbc with a pro charger for my in ride or a ls7 with kinsler fi.

Yeah I was looking at the warhawk motors too. Pricy but oh what a motor.

[rocketman]

well I have a new ls7 crate motor,but I also have a tall deck donavon block too.so I haven't decided.

Give me one :D

Scott,I'm kicking around the idea of building a 427 sbc with a Dart Iron Eagle tall deck block. Tell me more about your header fitment problems. I would like to keep my Hedman headers,if possible.

[XcYZ]

Clint, I was using a set of Hooker Super Comps and the issues I had were:

1. the #1 primary hitting the pitman arm retaining nut
2. clearance for the upper control arm mount bolt
3. the collector on the right side touching the floorpan (because it was indexed differently than the left side)
4. couldn't run a 3" air cleaner (but I was also running a tall single plane)

All the fixes were pretty easy, it was a matter of 'massaging' the headers and running a K&N X-stream lid. Another thing to keep in mind about the Iron Eagle tall deck is that since the pan rails are spread .800", there's no provision for oil filter built into the block, you have to run a remote oil filter. No biggie, though.

[USAZR1]

My car has a 3" Glasstek cowl hood so I hopefully wouldn't have any intake clearance problems. Would probably run the Dart tall deck single plane,though. Running a remote oil filter would be easy but I'm wondering if that block has provisions for my manual trans Z-bar. Not interested in having to convert to a hydraulic clutch set-up.

[XcYZ]

It will definitely fit under your hood. I have that intake and I'm 99% sure I won't be using it with the turbo setup, so if you're interested in it down the road, let me know.

The boss is in the block for the clutch Z-bar pivot, it just has to be tapped. I used the stock linkage with my 434 and the TKO and it worked great.

[USAZR1]

I'll keep you in mind on that Dart intake,Scott. Thanks.
