Yesterday my dad took me to have my Lisence Revised and we got to talking about horsepower..

He told me about one of his buddies who built a 800 hp big block and we stopped buy there on the way home..

Well we all shot the sh*t for a while and my dad noticed a Engine on a Stand.. We ask him what it is and he said oh its a 355.. My dad asks about it he said it was built for a old project he has going and its never been started.. Its a 327 block bored to a 355.. He said it was a built buy a guy who builds sprint cars and its a 450-500 horsepower engine. he dug up the receipts and all the work was done at Teeniers Engine Inc? he had 3800 dollars put into the machine work alone. my dad offered to buy it off him..

The engine is complete except a carb Its in a bag.. the guy said he will take 2500 for it.

Will this engine bolt right into a 3rd gen 87 z28 4bbl?

 

yep, it's a bolt in. 327 is a fairly desirable engine fopr those that like to rev due to their shorter stroke/large bore. If it's built right 7000rpm should be no problem

 

[FYI ON]
...and the last production year (1968) of the 327's had motors built with "LARGE" journal cranks and small journal mains! Those larger main journal cranks are the most sout after 327 3.25 inch stroke.
1969 and newer small blocks all have the same dia main Journal thru the GEN 2 LT1's.

[FYI OFF]

 

My dad said if I want He will Give me a lone for the Engine.

How hard would It be to switch the Fourth gen over to the Old school small block with the Demon carb?

 

I know this about swaping a early style sbc in place of a LT1.
The driverside motor mount sits in the same location on early and late (LT1). Its the passenger side that differant, It sets further forward than a LT1. Golec made a plate that bolted into the stock frame mount location then drilled and taped the 1/2 plate to accept the frame mount side in the required early position. also had to space up the drivers side to match passenger mount height

 

Ive never act. done the swap or anything, but Ive always heard that the eng. mounts on teh block are the same. its the mount itself thats diff on the 4 gens.. go to 3rdgen.org and talk to someone who has done the opposite swap. LT1 into 3rd gen. see if they had to make spec. motormounts.

as for the eng., sounds like a steal to me. depending on the act. hard parts inside. what kind of crank/rods/pistons? if they are forged, your not goin to come close to matching that price for a complete eng. minus carb. I wonder, does it have the orig. crank and bored out cylinders, or did they just get a 3.48" stoke crank for it? if it has the short crank, big piston combo you made it sound like, then it will wind up nicely. if it has a bigger crank in it, then all he made was a typical 355, like mine. what heads are on it and what cam? those two things will determine the operating range of the eng. (or at least where the power peaks are). my eng winds up to 7500 rpm no problem, feels like its still pullin, but track testing hasnt showed any improvements over shifting at 6700 rpm. so why bother. but again, thats just where my combo runs out of steam. not due to the size of the crank or pistons.

have fun what ever you decide to do.

This engine is awsome roller everything. From my understanding its built for a sprint car.. Sprint cars dont have Flywheels so he one specially made and lightend.. Its borred .30 over But it still has the 327 crank he said its a 7000 rpm motor.

I saw the reciepts and this engine was built for a race car..

Im going to call the engine builder today and get more info.. If my dad doesnt buy this Ill let you guys know It sounds like a pretty good deal on a 450-530 hp engine. Any that might want it let me know.

Hey had Bill Mitchell build him a 800 horse big block and he said The engine alone cost him 14,000. This guy doesn't cut corners

 

I have a nice Pro Systems carb For Sale if you need one. It has just been all freshened up. I have the receipt and tech sheet on what was done.

A bored .030 over 327 is a 331, not 355. I had one myself and there are a lot of similarities to a 350, but the rod size is different, so are the pistons. if it's a 67 or younger, it's a small journal crank with 2 bolt mains. if it's 68 or newer it's large journal, 4 bolt mains and doesn'r spin as high. The small journal was the most sought after due to it's abiltity to rev to the moon per say. And 400 or more horses is easy to reach, but you need single plane intake and a 750 or better carb on their to achieve it. Get the casting number off the rear drivers side of the block and I will tell you exactly what it is, as far as 2800.00, give me the numbers and let us know what was put into it before you dump a big sticker on it.. 350 with a 327 crank is a 302 If I remember correctly, 327 with 350 crank is a waste of time 305 with 327 crank is 283. 355 is a bored 350 .030 over...

 

Actually, if I remember correctly, a 302 = 327 block + 283 crank. I could be wrong, though.

 

I think your right, actually you are right..
