Im tossing around some engine ideas to possibly utilise parts I already have and could use some guidance possibly. Is it possible to use a LT4 intake on a standard SBC but with 23 Degree raised intake port heads. I know the LT4 has raised intake runners and i think the same bolt pattern, but im not possitive. I know about the other mods to convert the LT1 intake to a standard SBC as I know they will also aplly. Is anyone else running raised runner heads (aside from vortec style) with EFI/TPI setups?
thanks for any advice

 

I think you could use the Lt4 intake on a set of heads like the GM fastburns as they have a raise runner intake.

Not sure that would be worth while since an LT1 intake on a regular gen I head will provide same performance if not better performance if you use a better head than the fastburns.

Finding LT4 intakes is harder to do than LT1's.

I dont know of any other raise runner heads that one would be using on a street style sbc. AFR had the old 215's and I think trickflow had some at some point. Most dont use raise runner stuff anymore.

 

All Pro, the KING of raised runner heads.. Lots of people are using them.

 

Yeah but their normal 23 deg stuff is just as potent for a street/strip sbc. They make a good 220cc head that will handle 90% of most street builds. I dont know if the LT4 intake can even be ported to handle a head like the raised runner 245cc heads they have. The intake port may be very large for the LT4 to even cover. That head is a max race head IMO for 400-440+ inch motors turning 7500 rpm or more.
