The previous owner of my 1970 Malibu had a supercharged 454 installed that not too long later got stolen, and the original 307 was replaced (he still had it). Now I've had people tell me that you need stronger shocks to support the added weight of a 454, is this true? I asked the previous owner, but he said he didn't know. Now i'm wondering if I still have the 454 shocks in it, and how do i find out? If they are in there, does this affect the performance? Thanks.

I don't get you line here, the 454 was stolen out of the car, and replaced with the stock 307? Or the blown 454 was stolen , and replaced with a regular 454? Shocks are shocks ,basically. The springs are what you need to worry about,in supporting the extra "Girth " of a big block.If it has a small block in it, leave the small block springs in, or replace them with new ones for a small block.If it has a big block, you should put big block springs in it to help with the lowered front end.

The blown 454 was stolen and replaced with the stock 307. So now i have the small block, but i don't know if it still has the big block springs in it. So does this affect anything if the big block springs are still on?

The way it was stolen was vaguely as follows: the mechanic who installed it did it for an outrageously low price (some where around $1000 for the whole shebang.) and then he was the one who later stole it. I'm not exactly sure how it was worked out, but i know the original 307 was replaced.

Strange.
I doubt the springs would have been changed. If the front of your car is the same height or lower than the rear, then don't worry about the springs, you're fine. However, if the nose of your car sits up in the air, then I would say you do have big block springs. If so, a set of small block springs should restore your car to the proper ride height.

Does it sit level, or does it sit high in the front end?With big block springs , it should sit up high.You could leave them in there, but it could mess up the alignment , if you carried it to have it alligned that is.

Bistle, yeah the shocks won;t matter, it's the springs and sway bar that will. My 67 has a 1" front sway, which I believe is the heavier BBC bar vs. 7/8 for SBC. But if she doens't sit high in the front, don't sweat it.

I know this should be in bench racing, but it really follows this topic of how a motor could be stolen!

Back when my dad and uncle were in their late teens-early 20's, my uncle bought a car from a somewhat shady used car dealership in town. Shortly after he got the car, the motor went to hell. The owner of the car lot had "gauranteed" that the car was A-1 excellent condition (It was an old Ford), and as the story goes, when they went back to the dealer to get the car fixed or get some money back, the owner refused! So, since the guy had gauranteed the car's condition, and wouldn't back it up, they felt compelled to honor the warranty themselves. My dad, my uncle and a friend went to the car lot one night, and "stole" a whole engine right out of another similar car, along a busy street, to replace the blown motor in my uncles car! I wonder if this is the kind of thing bistledink was talking about with his chevelle?? Before anyone gets mad about me talking up the stealing of car parts, the car dealer is still around more than 30 years later, although he doesn't deal cars anymore, it's pretty much public knowledge that anything the guy does is totally unethical, bordering on and sometimes actually being illegal!

Actually, she sits just fine, so i guess they didn't have the big block springs installed after all. I guess i should have figured she would sit high, but anyways, thanks guys!
