I'm not sure on that one, you may have a little better luck by doing a search for chevy V8 specifications... are you looking for an exact one, or are you just interested in putting an aluminum one on yours? If thats the case, get an edelbrock one off of ebay... most go for about $75. If you are looking for low end performance, get the Performer intake. If you are looking for mild racing type of RPMs, get the Performer Plus... If you are going after all-out racing performance, then you are in the wrong forum, lol...
hope this helps a little...
