Tim240z Posted January 10, 2004 Share Posted January 10, 2004 Are they the same size (port wise)? I have 4.3 long block and am going to HiPo build my spare SBC and am thinking of using the LT1 intake, converting it to distributor, and running FI with Megaquirt/spark. Don't know what I'l put it in to, but what the heck.... maybe my truck?..... Tim Quote Link to comment Share on other sites More sharing options...
Guest richz260 Posted January 13, 2004 Share Posted January 13, 2004 As far as I know the only differences between the 4.3's & the 5.7's is the throttle body bore diameter. For more details contact John who basically pioneered the LT1 intake conversion at: john@lt1intake.com If you haven't checked out the site yet.... tak a look here: http://www.lt1intake.com Popular Hot Rodding also did a story here at: http://www.popularhotrodding.com/tech/0803phr_beast/ I got my '95 Caprice intake as a complete assembly from a junk yard for $75.00 !!! 8) Quote Link to comment Share on other sites More sharing options...
