Just a couple questions. I want to get a bigger engine, but i wan't to keep my t-5 because i don't have the $$ for a t-56. I was wondering if a World Class t5 coule handle the torque put out by a 327 TPI. Also, does anybody have a parts list, prices, or weblinks to anything about 327's. Thanks.

I don't think you'll have any problem with that unless you build it up for massive power. 327s have a shorter stroke than a 350 and thus produce less torque (but are able to make good power none the less). Plus, the world class T5 is stronger than the plain jane T5.

I have a 327 in my '66 GMC pickup and I think it's a great engine even with the 2bbl carb that's on it.

I believe the engine mounts are closer to the front of the engine so you'll have to consider that during the swap.

You have to be careful about your definitions. You are absolutely correct about the lower torque, but only at lower RPMs. Then the longer stroke engine torque curve begins to fall off at about 5,100 RPM, that "little" 327 torque will just be getting in the groove, and will maintain a whole lot longer. Makes me wanna go out and do a 6,500 RPM clutch dump just thinking about it....

Engine mounts are identical in every way. Just use the ones that came with your car on it.

The 327 is a great engine. The only thing is, the 350 is better. We all quit building 327s when 350s became avaliable, because every penny you spend on a build-up is multiplied by the extra cubic inches. i.e. why spend $2000 rebuilding a 327 and getting 300 ft-lbs and 325 HP for instance, when you can spend the exact same money on an otherwise identical 350 and get 325 ft-lbs and 350 HP. But if you already have one with a usable short block, it would work fine.

Its torque vs. RPM characteristics are not ideally matched to the TPI though. You will waste its most useful characteristic, namely the ability to rev higher and produce useful power, than either a 305 or 350. It has the same bore as a 350 but ¼" less stroke. But again, it should work fine.

Parts list, price, and links are all the same as for any other small block Chevy. Heads, cams, external parts, valve train stuff, etc. all interchange with any other SBC.

Personally I see no point in going to extra trouble to reduce the effectiveness of an engine build, for the reason you mention. The T-5 will last OK behind a 350 if you avoid shock-loading it: i.e. no 6000 RPM launches (not that a TPI motor will do much of anything at 6000 RPM anyway), and no speed-shifting. I have one behind a 400 that is hanging in there.

Sorry 'bout that! I guess you learn something new everyday - as you can see by my number of posts in the last 2 years I do way more reading than I do posting (and I've learned alot!).

so a t5 will do ok behind a 350. I never power shift anways so i dont think that would be a problem. I just want to know if it can handle the torque of normal race driving. Is there anything that can be done to make a world class t5 stronger?

K, i found 350 for $50 and a 327 small journal crank for $25. What length rods and what type of pistons should i look for? The block is from a 70-78 pickup, will the oil filter, knock sensor, and oil pressure sender still hook up?

well your 1st prob with that is that your block is a large journal block and the crank is small journal. get a crank out of a 69 327 camaro or any 307 (as long as it isn't a homemade small journal 307). as far as rods and pistons... as far as staying cheap i'd go with 5.7's and keith black flat tops or the ones with .100 domes( i got the domes)i think the ft's are 10.0:1 and the domes are 10.5:1. if money's no prob then have fun
