Yes the 55 is stripped down. It even has plastic side windows. I think I will leave it nostalgia, and bracket race and street rod with the 454 as is. But, a small block is so much cheaper, and a mild build would be reliable, and still fast in a light car. I don't think I want to go faster than 10's for now. Mostly because of the extra certification below 9.99. And also, because of my experience level. 12.5 and 107mph seems pretty fast to me for now. Don't want to overdo it too soon!
With what it would cost to get the 55 faster, I'd be at 1/3 to 1/2 of the cost of a smaller car anyway. Say it cost 5-6 grand to upgrade my 454, or maybe I could get a SBC powered rail or altered going for 10 - 15. I did find one site that offers a rail package formed and tacked together. With all the upgrades, it goes for around 8. Basic bare package for 3 grand. I already have a Powerglide ready to go.....
