Many. 348 would be a small block, whereas the 454 is a big block.
yes there were a few 409's made in 61 but they were rare as the 348 was the big engine back in 61.
That would be the first year 348 engine, 1958. The 3732811 block was used only for that model year. It came in passenger cars and was available with 250, 280 or 315 HP.
the Range of a set of numbers is the difference between them. in this case 378 - 348 = 30 Range = 30 that's as far as i understand it anyway. happy to be proven wrong :)
NO! The 427 Chevy engine was not sold by GM until 1963. The 427 is a big block engine and the very first big block was the 348 introduced in 1958. The 409 was introduced in 1961. The 427 in limited production only in 1963. The 427 was later released again in 1966 as a production engine. The largest engine every offered in the 1957 Chevy was the 283 V8. You could order this engine with mechanical fuel injection in 1957.
348 Lbs.
I can find no evidence the 409 was installed in any Chevy or GMC truck. The 348 was used in Chevy trucks and the look almost identical to a 409. But, I cannot say positive that Chevy never put one in a truck. Further research is required to give a definitive answer.
348 miles
No. But there was a 348 cubic inch big block which equates to 5.7 liters.
About 348 miles.
The 5.7L Hemi motor is 348 cubic inches.
25% of 348= 25% * 348= 0.25 * 348= 87
