I've literally built hundreds of engines, both chevrolet and ford, and both have their advantages and disadvantages. Chevy lacks on their blocks due to the lack of deck height. You can't get a good compression height on a piston with a 4" crank without using 5.850 rods, unless you want to fork out the cash for a tall deck height block. Fords have 9.5 deck height blocks, and you can put a 4.250 crank in them with a 6.200 rod and still have a 1.700 compression height. Its all about how much money you want to spend. As far as an all out race engine, I wouldn't even consider an lsx engine. It would cost entirely too much to make the durable hp that you could make with the standard sbc. I've built plenty of $1500 short blocks for customers, and I've built $8000 short blocks. Its all in how fast, and for how long you want to go. And as far as aluminum blocks go, there is no advantage whatsoever other than it being lighter. Building a 1200hp aluminum small block nitrous engine would be stupid. The aluminum small blocks aren't strong enough to support the hp.

Ya lol +2... Thermal Dynamics play no role with internal combustion engines
Actually I think its the other way around. People crack me up when they make assumptions like these.

Not without a lot of fabrication. I've done this, and it isn't a "bolt-on" head by far. For the average Joe, it would end up costing just as much, or more than the equivalent aftermarket sbf head. I'm thinking that may be why he hasn't posted anymore info on it in a while.

I wanna see an auto ls1 with cam intake and exhuast putting down 400-450rwhp and thats with a mild cam. He says with something more aggressive the numbers will go up. Maybe I could see 400 or just a little over. How can you be doing something thats pretty cool and then get something so simple messed up. oh well.

I got everything to work. Had to offset mill the top head bolt holes, mill the pushrod holes, had to mill the underside of the intake runners so the pushrods wouldn't hit, and then had to make a sheet metal intake. Fords are opposite from chevrolets with their cylinder offset. #1 on a chevy is on the drivers side, and #1 on a for is on the passenger side. If it weren't for that, the LS intake would work fine. You can't get a ford intake to work because on a ford head, the intake runners are centered on the head, and an LS head they are off to one side, which make the runner spacing way off.

Sounds to me like I am talking to someone that has only built old *** fords and chevy's . I guess you can't teach an old dog new tricks. I'm not here to convert some die hard ford guy into running LSX powerplant's.Hell us real GM guys enjoy out running the **** out of you. And is anyone else getting tired of ford guys jumping on here talking **** about our cars. I mean after all this is LS1 tech . Not P.O.S ford.com. You haven't seen me in any mustang forum have you. That's because there isn't anything in there I need.I wouldn't think I would have to explain why the LSX series engines are the better choice.But if it makes you feel better, hell yes I think ls1 heads will be a big damn improvment to a SBF.All I was original stating was why stop there .Why not the whole engine since you are already selling out any way.
Would it still have a ford sound since it keeps the ford firing order?
