RyM3rC Posted August 12, 2013 Report Share Posted August 12, 2013 http://www.columbusracing.com/forums/showthread.php?t=113668 There was no vortec motor in a 92 anything. If all you're going by is the centerbolt valve covers, the vortec heads are very popular swaps onto earlier SBCs, so I'd look into a little more than that. Do you have any more info, casting numbers, pics, anything? Quote Link to comment Share on other sites More sharing options...

Well I can't see the casting numbers on the block or heads ...I can get a pic when I get home ...I can tell u that it is a surp belt setup..and not a v belt setup..I had the valve covers off of it.. that's about it..

Green Bastard Posted August 12, 2013 Report Share Posted August 12, 2013 Fwiw, center bolt heads aren't necessarily vortec heads. They are likely the factory heads on the motor you have, Chevy used center bolt heads from 86.5 on. Quote Link to comment Share on other sites More sharing options...

gt-titan Posted August 12, 2013 Author Report Share Posted August 12, 2013 so what i have is a LO3 prob from a 92 like i was told,,, it is not a vortec motor......it is a 305....5.0 ltr ok now can i put a set of vortec heads on this motor... and is the intake on my motor different from,,, say the intake for a older small block motor,,,the reason i ask is because four of the intake bolts are not angled and all the intake bolts on my sons intake are all angled Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted August 12, 2013 Report Share Posted August 12, 2013 You can drill the manifold to fit the other style heads, just use washers when you bolt it on. Quote Link to comment Share on other sites More sharing options...
TA In Progress Posted August 12, 2013 Report Share Posted August 12, 2013 I know at one time there was a Vortec TBI manifold available from GMPP. Not sure if they still make it though. It was in the Jegs catalog. Quote Link to comment Share on other sites More sharing options...
Chadz89GTA Posted August 12, 2013 Report Share Posted August 12, 2013 i believe you are right man....my motor looks just like a LO3 motor..... Same heads different intake. http://Http://www.thirdgen.org please go educate yourself. An L03 is nothing but a tbi version of the L98, basically same heads but one is a 305 and one is a 350. And yes those heads look like l98 heads minus the cable covers that someone swapped. If you try to put a normal intake on it I bet it doesn't fit and you'll need one one for the funny angle l98 style heads. Quote Link to comment Share on other sites More sharing options...

Make sure you seal the shit out of where you drill it, some intakes dont like when ya try to make them fit those heads lol Quote Link to comment Share on other sites More sharing options...
Cordell Posted August 13, 2013 Report Share Posted August 13, 2013 This will likely come off like I'm an asshole and I'm sorry. Why are you so dead set on messing with this thing? It doesn't look like anything special, it's a factory serp setup, and a crappy TBI. If you want to make more power lots of things are going to hold you back, like the TBI, or the fact that it's an underpowered 305. For the amount of effort if you want any real power gains get at least a 350, your shit will all bolt up, but do something other then that weak ass TBI. Trust me you'll be happier, the way it sits I'd be shocked if it dyno'd over 200, why not make a solid 300+? Okay I'm done ranting, carry on.

Browning Posted August 13, 2013 Report Share Posted August 13, 2013 Sinking money into a 305 will huge a waste and a huge let down. We built a mild one in high school and barely noticed a difference. Where as the same work on a 350 would have been a nice improvement. Looks like some did a decent job seeing as you styill have a/c and such. Why not invest in a stand and go from there working on a replacement engine for the future. Then keep the 305 on the backburner just in case it's needed later Quote Link to comment Share on other sites More sharing options...
