Figured the sb would be easier,since A bodies were optioned with them . Thanks for all the perspectives on the subject. They were optioned with big blocks, too. not after 69 That's completely irrelevant as the engine bay did not change. You also don't have to buy expensive headers or any of the other expensive parts. If you don't mind a little fabrication and you're not trying to grab every last bit of horsepower the car can bebuilt rather cheaply. Outside of the purchase price of the car and body/paint/interior I'll have the 440/727/3.23SG 8-3/4 in my Barracuda convertible for well under $2k, probably under $1k. Yes, the 440 was basically free and I can build the 727 for about $100. I can also build the $20 73-76 k-member into a Direct Connection unit for very little.

I had a 68 w/ a 383 butttt it had no fender wells I could pretty muh stand up in the engine bay. My freind has a 69 500 wedge fender wells..it is a MoFo to work on. My 72 w/ a 340 was a piece of cake.

Well I see a big heap of body roll there and a couple cones knocked over, does look like fun though I am not causing global warming, I am just trying to hold off a impending Ice Age!

There would have been the same amount of roll with a small block. We also had a lot of grip with the tires.......

You would be able to keep ac ps and original shifter on the column and exhaust is available at a reasonable price. The big block has an awe factor but it is a load of extra work and extra costs. You won't be able to use a/c. You will have to add a floor shifter and find headers that will need reworking. BB is very hard to work on in an A body. You could always put a cam, headers and 4bbl on the slanty and have some fun. "You won't be able to use a/c" My S6 a/c and hoses, radiator hose, all wiring, PS pump, and throttle cable fit perfectly...see pic Russ:) 4536715-IMGP1306.JPG (81 downloads) BigBlock 74 Swinger

Might get away with it with a SB. not with a 727 , the Z bar for the shift linkage is very hard to find I swapped in a 360/727 in my 71 valiant. I used the column shifter and it works perfect. I had to do alittle bit of fabricating and adjusting. It wasent a big deal.

He dropped in a 727/383BB and used the 3 speed on the column shifter. He disabled the part that made it slip back in the 1st and reverse side so it just slid up and down on the 2nd and 3rd back side. Ive seen it, believe it or not. Last edited by 71valiant; 07/07/08 09:49 PM.

I'll let you know pretty soon on the RB install, I'm guessing my 500 inch RB will likely be tough to work on, but probably no worse than the 355/angle plug small block Pro Street Vega I had back in the early 80's. I drilled holes in the area where the bellhousing bolts were just to pull the tranny a little more easily! If I'd've known it was gonna end up in an a-body, I probably would've built a 416 instaed.... https://i.imgur.com/tmuGzov.jpg

If you haven't wrenched on these cars a bunch - go with a stout small block. They can make a ton of power, are well balanced (compare to a BB) and most all of the parts you need will be relatively cheap.
