TBI Heads on a 1970 Block Carb'd
Looking to put the old TBI Heads on a 1970 Block, I bought it smoking with 305 heads & while apart thought I'd put on better heads.
14102193 65cc TBI 1.94 intakes and 1.50 exaust GM 391467 350 small block Thinking of a dual plane intake with a Holley carb Been looking around the forum, & I'm flooded with carb to TBI computer stuff, to TBI to VORTEC, & though having 906s, planning to stick with TBI since my light foot seldom goes over 2000 RPM. Seeing if anyone has any advice for a cam, picking a gasket, or anything else you'd like to impart. Thank you. |

I have no information. But if you don't get a responses try reposting on the engne side of the forum. I have had success there in the past. Or look to the years the TBI came installed from the factory.

You might try SS454 or Harris tuning.

Dual plane with a Holley?
Edelbrock 2701, dremel out the 2 center bolt holes on both sides, Holley 600VC Dual plane with a Edelbrock? Edelbrock 2701, dremel out the 2 center bolt holes on both sides, Edelbrock 500CFM Edelbrocks tend to run richer up to 4000 IMO, hense the 500cfm Tbi- Stock "K engine code computer" 1987-1993, stock intake for 1987-1995 , Edelbrock 2102 cam and lifter or equivalent engine harness https://affordable-fuel-injection.co...iring-harness/ 2701 |

Re: TBI Heads on a 1970 Block Carb'd
Thank you warren, we are on the same page about carburators on an intake. (The 2701 is for 1986 blocks on down & as you said need to be modified, 2104 is for 1987-1995 -which I need for my 1987-1995 tbi heads. Worse case scenarioI go with stock heads & an adapter plate) I offered a guy his asking price the last 2 weeks but I just get the run around. But there are other fishes out in the sea! Thank you guys for your advice.
Also not doing the tbi electrical hookup... 3 spd on the tree, carb... what's to hookup? For anyone trying to do something with 193 heads, I changed my search to 14102193 & in hotrodders.com found BogiesAnnex1: ...they will take to a cam up to about 200 on the intake & 215 degrees on the exhaust with 110 degrees or more of Lobe Separation Angle LSA... * You want an aftermarket set around 4 degrees advance will pick up even more bottom end for ya . Thirdgen lookup fast 355 He suggests a F/Y car LT1 cam or similar aftermarket cam Like The comp 4x4 206/210 @ .050 or Elgin E1136 .. *OEM ... timing sets are indexed about 4 to 6 degrees retarded Last edited by Andrij; 12-20-2021 at 03:38 PM. |
