How much improvement will a alloy intake and extractors make?and should i go for four into one or try y style pipes.I want to leave the original hood on vehicle.Thanks.

Welcome Vic!!

I've always heard that an intake change & headers are usually a good improvement, esp. the headers. Most of the ones I've seen are the 4 into 1 type.

Thanks Sid, for your reply. :)

I like 454 Monte Carlos, what year is it and do you have photos?

4 into 1 are the most popular and have the most engineering for big blocks.

Aluminum intake will save a few pounds and add a few horsepower.

It sounds like you have a fast car now. What time are you trying to achieve in the quarter mile?

Hi tim, the monte is 1970 ss 454 auto. I just purchased the vehicle it has been in Australia for some time. I will be using bolt on parts hoping to run in the high 12's.Thanks for the interest.Send me your email adress to send photos. Vic.
