I am new here and I figured this would be the place to get some good pointers and ideas for my build
Project-
I need to wrap up my frame off rest on my 73 vette with the perfect engine. I want to build a 427 sbc LS based engine or something recommended by those with experience on the board. So which to choose LS2, LS3, LS6??
I can fit a Magnussen supercharger under the hood also so I will use this to get the power levels up. I need help with picking a combo that can yield 600-750rwhp and streetable.
So what parts would you pick???
1. displacement
2. heads
3. Engine management
I want to use parts that are the best and most easily accesible?
Thanks

FWIW, have you ever driven a 700+rwhp 70's Vette on the street in anger?
If it were my car, I'd do up a single-plane EFI 402-408 inch LS engine and make it look as much like a BBC as I could. 500+ at the tires has been done relatively easily and it is super-streetable. It ain't slow either!
To each his own.
Good luck.
Jon

LS3 with a TVS 1900 on top sounds like a lot of fun to me. I had a '73 vert back in the day. Low compression 350 that barely had enough power to get out of its own way. It was good lookin' and produced a lot of memories . Had a soft top and removeable hard top. A classic like that with 500 hp at the wheels and perfect street manners would be a blast. If you could fit a 5 or 6 speed behind it, that would be the ultimate fun ride in my mind.
They are just now bringing the newer magnuson blowers to market. I had an mp 112 and now a 122 on 5.3 & 6L truck engines. They snap a 5000# truck around with ease. A 3000# vette with a new generation magnuson on top would be scarry fast.

if you check out the february 09 issure of HOTROD they show a chevy small block new block from World Castings that accepts LS cylinder heads but uses standard chevy small block architecture. its called the Motown LS hybrid . the engine in the article had a 4 inch stroke and 4.125 inch bore (427ci). heres a quote
"The very first pull on World's dyno netted 629 hp and 579 lb-ft. That's about 70 hp more than one of World's regular Motown small-block 427s and about 15 more than the company's typical Warhawk LS combos."
the heads are ported World Products Warhawk LS-1s, any LS intake bolts right up because it has an LS-production deck height, and the distributor drops in at the rear like a sbc but uses the firing order of a LS.
thought that article was cool and if i was doing a frame off resto thats what id go with.

Yeah I read that article. Very interesting. There have been have few good articles in there lately. Did you see the one about the Salem speed shop?
I might take a drive and go check it out just to talk to the guy.

I have had a few different vipers so far in excess of 900rwhp so I know that 600-700rw would be a strong target for the ole vette . Im hunting the right fit now so keep the ideas coming.
