What kind of mileage does a 454 get? AND do you know if a 454 will go into an 1989 Chevy K2500 with 4WD to replace the 5.7 Liter V8? By the way. VERY COOL Vid!

Thanks,

Yes, a big block will fit and the bolt pattern should match the transmission. towing or not we would get around 10-12 mpg.

u shoulda taped the process. i could use the lesson

[Microillusions]

didn't have a decent video camera at the time :(

hahahah..i thought u were gonna put this in ur truck!!!

[Microillusions]

Nah, The 454 was rebuilt before i had a truck. Although that 454 would have enough power to move my truck along nicely.

383 Tbi Vs 454 Tbi.. What would you reccomend? Going into a K5

@TRILLGATES2K6 Oops I didn't see you were talking Lsx-type Ls7... That is a totally different engine with modern intake ports, modern twin swirl combustion chambers, individual ignition coils, cranktriggered ignition on several spots (4?) and a hydraulic roller cam with hydraulically self-adjusting timing... if I'm not misstaken? They're 40 years apart in technology AND politics - and it shows.

@TRILLGATES2K6 the LS7 was a 454cu.in. It had very similar specifications to a 2nd design L88 (427) except for the nominal 4" stroke and the externally balanced crank - as opposed to all other BBCs, that were using internally balanced cranks and nominally 3.766" of stroke, at the time of the LS7 was introduced (1970).

I have a big block and it doesnt matter if i am just driving it or towing a 8,000 pound trailer it always gets 11 to the gallon haha. Fuck el nino

[ultaMMA]

should have done chevy orange instead of black but still looks great

[TRILLGATES2K6]

@rivbro91 Actually this is more engine than an LS7. An LS7 is only a 427 cu in. and of course this is 454 cu in. But that doesnt really mean shit. It comes down to the heads, the compression ratios and lots more other shit too.

@Microillusions Thinkyou can do it again if you ever rebuild another? but have it recorded.

[killshotnation]

@InitialDirt this isnt even an ls engine, it doesnt have the same compression or anything, do you know anything about these? and who the fuck cares about mileage in a big block anyway, if your worried about mileage then go get a pansie ass lil 4 cyl

[rivbro91]

@InitialDirt This is nowhere NEAR the same engine as an LS7.

[jboydmv90]

Did you overhaul it? or was it a performance rebuild?
