BBC will always make more power and can hold more power but again with all the fitment issues that your going to have and the cost to build a BBC id say a turbo LSX car would be better because of the aftermarket. It was a pain in the *** to just fit a BBC into my dads 69 Camaro so to try and fit half the engine under neath the cowl in a 4th gen is gonna be 100 times worse. on the upside to that you will have to cut a lot of things so your gonna lose weight on the front end but that should voided with the added extra weight of the BBC. Either way you go good luck and please post pics Ive never seen a BBC in a 4th gen and it would really look cool IMO.

It's going in my 61 Bel Air. It's originally just a 283 car, but it's had a 433" (427) for about 15 years now. I've owned it since I was 15 (40 now) and have been looking for a 409 since I got it. Took me that long for the right one to come along that I could afford. That all aluminum one in the pics I posted was just completed a few weeks ago and made over 850 HP and nearly 700 TQ with less than 12:1 compression. The other one pictured is a street driven build, but still a solid roller motor. It made 604. I'm shooting for around 650 with mine. (Or about the same as my current big block, just in a cooler looking and lighter package.) You could build one based off of a 348 block for about half the cost of a 409 and still have the same look and make great power. It's easy to get 434 cubic inches with only a .030" overbore out of the little 348 with a stroker kit. The 348 weighs more than a small block, but still lighter than a regular big block.
^^^Beat me to it.

No offense, but putting a big block chevy into a 69 Camaro is about as easy as it gets. Not one piece would have to be fabricated or hard to find. I've never put on in a 4th gen, but I have researched it and the only things you really need (besides deleting the HVAC and getting a firewall block-off) is an aftermarket K-member and headers. You can even start off with an off the shelf header and have a few tubes redone to come out somewhat cheap on the headers. I see used sets come up for sale here on LS1tech every now and then too. Clearance for a carb is an issue, but people make them fit.....just like they do when running a tall Edelbrock or Holley EFI intake on an LSX in a 4th gen. An edelbrock Torker 2 intake is super low....so it should give the most hood clearance available. You can also space the k-member down just a tad to gain some more clearance.

Good info btw thanks man!! My dad has the Torker 2 intake actually on his 454 Camaro he doesn't like it tho. We all think that between his cam (which im not sure on the specs but he called Comp Cams to get one of their Thumper Cam's) his intake, and his carb that it doesnt match up right so that is the reason why it's not running right. So he is considering rebuilding it and has a few ideas in mind already.
