I just want to ask you guys and gals a question. I am seriously thinking about up grading the hp issue with my 91 cappy classic. I've searched and looked in here and most popular of course is to just swap out a LT1. The thing is, living right on the border, I have access to some very cheap 9C1 from the mexican police. What I'm afraid of is the whole comp swap out and for some reason, that opty box behind the water pump does not give me the warm fuzzy. I'm basically looking for a nice highway passing on demand car. I was just thinking about making the 305 a 327 which should make,with the proper stuff, 300 hp. And no I am not going to sell my faithful baby to get a beat up cop car that was probably beat to s**t and back with no remorse. I appreciate your info. Laters..

Thumbs up

Someone commented elsewhere that there are plenty of 383" TBIs out there. Check 3rd-Generation (I think?) Camaro forums for more info.

I wouldn't swap an LT1 either, I don't think. Might as well build a solid motor out of what you have!

an lt1 swap is very demanding for a TBI car. much more than just the engine needs to be replaced. but just about any standard small block can drop right in i suppose. an lt1 swap would be nice but other engines would be easier with same if not more hp.

(Sorry to take this off-topic a bit)

Blake-
Can you describe your list of "Ultimate TBI" mods? That's all I saw on your page. Thanks!

its an old trick the TBI camaro/firebird guys have been doing. basically, take a throttle body and dremel the hell out of it, to keep airflow smooth through TBI. smoothening opening of TB bores, grinding down throttle body shafts, etc.

they have a write up here:

no large gains but it cant hurt

another site for "ultimate TBI" mods

ozzy, have you thought about getting just a 350 TBI? probably find one cheap, and would be a very simple swap. a TPI engine might work well too but i dunno if that would be any harder...

but at least the 350 tbi would be very straightforward. but then again, probably not big enough hp gains to start off with...

Well, I have been eyeing a new engine for my 68 elky and I want to swap the 383 it has right now into the Caprice. I'm not to worried about the EFI because I'm going to upgrade that anyway. My primary concern is I would like to keep the seprentine belt sys. The 383 has Trickflow heads on it and I'm not to sure if it will fit the system. Any help will be greatly appreciated!

Oz, I'd be willing to bet that the Trick Flow's wouldn't be an issue. I have a buddy with an 89 Formula with a 383 TPI and an ATI ProCharger with Trickflows on it, and he has retained all of his O.E. serpentine system. HTH a bit. Good luck with the swap! Rahn

I'm starting to wonder what kind of power could be gotten from the L05, like with a stroker kit (waaaaaaaay down the line). Reading past threads with excellent advice from Ken Rolt and others, as well as what I vaguely remember from the 9C1 mailing list, it seems like the work doesn't gain too much. Vortec heads and manifold (and possibly distributor for clearance issues), Cadillac air "box" with Team SS-type cold air box, B-car LT1 cam, dual or big-single exhaust... all to get to the LT1's power or maybe a bit more.

Sure, it'd probably be cheaper than buying an LT1 car, but how about swapping a RamJet 350? Or what kind of power could one get out of a 383" or 396" L05? Any opinions?

383 is a great idea for the caprice. the torque will really help. Check out http://mcclureracing.com for their 383. it looks like a forged longblock would be around $4300 and if you contact Kelly R.(GhoSSt) he will set you up with the fuel injection. But yeah, for the money, the LT1 swap isnt the best bang-for-the-buck, more of a look what I did. HTH
