Guest FinalRights Posted September 24, 2003 Share Posted September 24, 2003 Anyone know the engine code? Also,I was wondering how much weight this would add to a 260z. How hard would it be to get one of these engines in the 260? Does anyone know the cost for install and a good place to find the engine. I'm looking at either doing this engine or a Vg30dett,to keep it Nissan . Edit: I'd do a search,but I don't know the engine code. Quote Link to comment Share on other sites More sharing options...
Guest Tom Scala Posted September 27, 2003 Share Posted September 27, 2003 Engine codes for 69 Firebird RAIV are WH -manual trans XN-auto trans 69GTO XP-auto WW-manual 70 GTO WA-manual YC-auto I couldn't find the 1970 Firebird codes Cylinder heads should have either 614 or 722 cast on center exhaust ports and all 4 exhaust ports will be round. The RAIV heads alone fetch anywhere from $1500 to $2500 depending on condition. Pretty rare stuff. Exhaust hookup may be a problem since noone makes a shorty header for round ports and I don't know if stock manifolds will fit. I've been wondering about a Pontiac swap since I have a fresh 68 GTO 400 sitting in my garage. They are a good bit heavier than a small block Chev. I remember someone on this site has a 455 Pontiac Zcar so it can be done. Quote Link to comment Share on other sites More sharing options...
Guest Chris Leathers Posted February 16, 2004 Share Posted February 16, 2004 You would be money ahead to grab any 400 block & put a pair of edelbrock aluminum heads on them. They're about $1,695 a pair complete and out of the box the will outflow a ported set of RAIV's. Plus with the alum. heads it would be lighter than an iron headed SBC. I would like to see this swap beings i'm a Pontiac nut myself. I have a Pro Street & Strip 74 GTO and a 63 Catalina. I recently purchased a 78 280 Z and plan to do the LS1 / T56 swap. Just scored a 73 Z also ! Good luck! Quote Link to comment Share on other sites More sharing options...
opie Posted March 27, 2004 Share Posted March 27, 2004 Agreed. Leave the RA IV to a numbers matching restorer. It's too expensive. Grog built a 350 Pontiac Z and had a site for it. 326-455 are all the same size. EDIT: Just found the link. http://hybridz.org/nuke/index.php?name=PNphpBB2&file=viewtopic&t=14762&highlight= Here's Rick's site. btw, the only advantage to using an aluminum intake on a Pontiac is weight. It flows very well up to the stock redline. http://www.rickeybell.com/ Quote Link to comment Share on other sites More sharing options...
