I recently converted my 69 from a 350 to a 454, I swapped the old front coils for a new set of big block springs from zip. They brought the front end back up to where it's supposed to be but now I'm building another big block for it, this time it's a 454 with an 8-71 blower. I can't beleive how heavy that 8-71 is, the complete assembly with carbs and all has to weigh damn near 200 pounds. I'm sure I'm going to need to swap out the front coils again because of how heavy that blower is, the blown 454 will weigh about 200 pounds more than the 454 that's in it now. Does anyone know what front springs I should put in it? I've seen lots of blown big block c-3's, I'm curious what front springs they're using. Maybe from a big block pickup truck? Does anyone know?

A guess, a coil over shock system that has adjustable ride height

Wow those are expensive. I've never used a coil over shock before, do they replace the front springs in the car or add to them? To be honest I'd really like to just replace my existing front springs with stronger ones that will support the extra 200 pounds that the blower is going to add.

they replace the existing spring and shock. Maybe someone else will comment on other options.

Best way to go unless you want to keep swapping springs to get the good ride height.

I went with the Speed Direct kit because I was removing weight the front end.

That might be the best way to go but it's also the most expensive. The six or seven hundred dollars I'll save by going with regular front coil springs can be put towards the engine build instead. If money was no object I'd go with the coilovers but my budget for this project is limited.

I'd almost have to say clueless if you are going to a 8/71 454. Everything behind the motor is going to cost way more than front springs

It's too bad you couldn't have gone with an LS that is lighter and makes more power than a blown 454. They are pretty pricey, but you'd have the right ride height.
