What year did they stop making the 327 engine?
The final year for the 327 engine was 1969. There were only two versions available, both with two-barrel carburetors.
How much HP does a 327 have?
Rated at 375 hp, the fuel-injected 327 was a high-winding screamer, as satisfying to drive as any big-block. At the other end of the spectrum, the 327 was also offered at much more pedestrian power levels, as low as 210 hp (gross).
Is a 327 and 350 block the same?
Re: 327 block same as 350??
Yes, the first 327 was a small journal engine up until mid 67, when they made the big journal crank. The 307 and 350 were all big journal. Even the mains were smaller on the small journal engine, so the big journal crank will not fit in the small journal block.
Did Chevrolet ever make a 327 4 bolt main?
No – GM never made a 4-bolt 327 for production use; many have been drilled and tapped for six extra splayed bolts with aftermarket main caps on the #2-3-4 journals by machine shops, but GM never made one.
Can you stroke a 327?
Your 327 has a 4 inch bore, so yes, you could make it a 355 or a 383. (also a 302, for that matter). A 1965 327 has a small journal crank, that is a factory “forged” piece. Your engine builder is making a 355 or a 383 by changing the crankshaft to a longer stroke, and replacing the pistons to match.
How much HP can I get out of a 383 stroker?
The 383 stroker engines have been reported to achieve 330 horsepower with 410 foot-pounds of Torque, 395 horsepower with 410 foot-pounds of Torque and 395 horsepower with 410 foot-pounds of Torque.
Is the GM 5.3 a 327?
The 5.3L is not a 327 or even close to a 327.
Will a 327 crank fit a 350?
No can do. As 47chevycoupe stated, the extra stroke length will put the pistons about 0.23 inch higher, or way above the deck. 327 stroke = 3.250, 350 = 3.480. Your 68 327 should be a large journal, but it might be small journal.
How much horsepower do headers add to a 350?
The length of the primary tubing determines the effective rpm range, but headers can be worth 15-20 hp on the right application. Run on our restrictive two-barrel 350, the headers improved the power output to 248 hp and 365 lb-ft of torque, with consistent gains through the rev range.
