I used the Monster Transmission external lockup kit when my car was running a 200-4r, I wouldn't recommend it, it locked up early and didn't like to disengage until about 35mph.

You will most likely need to run a spacer. My car currently has steel 15x8's with 4.5in backspacing if I remember correctly, and I use a 3/4in spacer with 275/60/15's

It'll just be a sleeper for now! If your trying to keep the stock hood, look into a drop-base air cleaner.

My .02 is stay away from spray and just search the web for an engine. I bought my 406 off of a guy on a chevelle forum for $2,000, and its been a 12.02 in the quarter. Nitrous is cool but you can find a pretty stout 350 for less most likely that will give you reliable hp without the chance of...

Pretty cool build of a bbb my mechanic did for some inspiration. He's now running it in his 70 gs. Said he could have made a little more but they didnt want to make the mopar engines from the previous episodes look bad! https://www.powernationtv.com/episode/EP2016-17/big-bad-buick

Love these cars! Looks awesome!

I am running a 406 in my car currently. It his a hydraulic flat tappet as well, cam profile sounds similar. I have trick flow twisted wedge heads on it, i believe theyare 195cc runners. Makes lenty of power and torque. 220's would be too large though as everyone else here has mentioned. As for...

I am running a Top Speed Performance (TSP) ready to run distributor on my sbc. Cost around $120 shipped on Amazon. Some people say they're junk, and if I had the budget I would have gone MSD, but for the money I spent it gets the job done. Pretty sure they sell Old's dizzys as well.

Sweet!

Like v8 rumble said, 4l80e is a good trans that can handle a lot stock. My dad just put one in his nova with a Circle D converter and loves it. It is an expensive swap though in terms of buying a computer and converter.

Typically the higher the stall on the converter, the looser it is with part throttle. This "looseness" is further exaggerated by lower numerical gears. Like everyone here is saying a nice 2500 stall conveter with your gears and the torque of the 455 would work well.

My car is a sbc and I love it. With a 2004-r and 342's i got almost 14mpg highway with an 850 double pumper and a heavy foot. Both are good motors, but with less technical know how a 350 might be a better option. Also, a 5.3 or 4.8 are not direct bolt ins, so while it may be cheaper to source...

Some will know more than me, but LS engines besides being 50 year newer technology have better heads out of the box as they start at 15* all the way down to 12* (ls7) valve angle as opposed to an sbc's 23* heads. Closer to zero the better the cfm all else equal. So thats a major difference along...
