Wow, old thread, I did the conversion but I built 540's its pretty easy if you understand engines, I know I don't have the article and more, if your just wanting to swap intakes and nothing else, Id stay with the MPI setup theirs really no HP to gain,

PM heatseeker. he was emailing it to people. but he only has 8 posts on here ever, so he is probably not lurking here these days. but odds are he has same email address and will get a notice to check for a PM or empty his inbox.

I'll give Heatseeker a try......Thx

Heatseekers mailbox is full....

If your looking for 500hp why not just do a cam swap with lifters, springs and rockers? I think stock injectors will support 500hp with an ecm tune.
