:roll: i have a 366T BBC would it be worth freshining up a short block assembly with mild cam and aluminum intake? I dont wanna get into alot of heavy machine work or would i be better of finding a SBC? with slight modification(cam,intake,slight boring)pound for pound which would be more reliable and have more torque? i dont wanna do alot of modifying (350 to a 383,406 or 366 to a 427,454)I guess what i need to know is which motor would be worth freshining up? thanx

There is not much in the way of performance stuff for the 366. As it's a tall deck you have to get spacers to run an intake. If it were me, I'd do the 350 as it's lighter and there is wider parts availability. A friend on mine put a 366 in a 65 pickup for his wife, it's very reliable...

I ran a few 468s with the 427 TD block because I could get them free, but as stated above, Your really carrying a lot of weight for just 366 CIs. :wink:

the 366 bbc is a waste of time and money. do not try to do anything with the block. the heads and crank are useful, to trade. you should be able to buy and build a 454 for reasonable money and out perform the small block.

I DISAGREE!THE 366 AND 427 TALL DECKS HAVE ONE ASPECT OF WEIGHT SAVINGS...BORING THE CYLINDERS OUT TO 4.250.....IVE EVEN HEARD THEY COULD POSSIBLY GO 4.375 IF SONIC TESTED!!!!

STROKER KITS ARE SOOOO INEXPENSIVE,CHECK EBAY AND SEE FOR YOURSELF,PARTS ARE STRONGER THAN STOCK STUFF AND IF YOU WANNA SPRAY NITROUS IN THE FUTURE THE FORGED STUFF CAN TAKE MORE NITROUS THAN THE EQUIVELENT SBC STUFF!!!


ILL NEVER GO BACK TO SMALL BLOCK FOR PERFORMANCE STUFF!!!

IS THERE ANYONE HERE THAT HATES DRIVING IN A BIG CHEVY VEHICLE HERE???????????? BUILD THE BIGGEST YOU CAN AFFORD!!!

LAY IT ALL OUT ON PAPER PROS AND CONS AND COST COMPARISON

Only thing I hate about a Big Chevy is the valve train.

I will NEVER have a big block!!!!!!!!! NEVER ,I love my rodeck BIG in. sbc. The weight savings alone is worth the extra cost!! There I said it ,now all the bbc's will kill me .I LOVE SCREEMING sbc's. Im an old comp.eliminater guy revvvvvvving to 10,000rpm 288's,the 296,i blew up past 11,000!!! Hurt the wallet but was a riot!!!!!!!!!!!! Wouldnt trade those days for nothing! BUT the main thing bbc or sbc everyone is different, it would SUCK if we all were the same!!!!!!!!!!!!!!!!David. ok bbc's have at me!

The 427 truck block already has a 4.250" bore, but I wouldn't take it more than .060" over, the cylinder walls aren't that thick. As for the 366, it's a waste of time and money. The cylinder walls are way too thin to bore more than about .030" without running into problems. Also, the 366 CANNOT be bored to a 427. They are also somewhat heavy compared to a standard deck big block. You're better off finding a builder 427 or 454 from a passenger car or pickup.

hey colorado race guy,have you ever seen by personal experience?


the eternal bbc. vs. sbc.....just remember one thing,the worse thing for a valvetrain other than common neglect,would be RPM!!!BBC MOTORS MAKE LOTSA POWER AT LOWER RPMS THAN SBC.

list out your pros and cons and cost comparison and also take into affect if you ever spray nos in a motor that with equivelent parts the bbc can safely take more nitrous safer..........ok your turn sbc lovers hee hee

If I could have a 565 inch small block I'd be right there with ya.


P.S. :shock: 11000 RPM
