Only accessory I have turning with the crank is the alternator. 390whp with what kind of cam? I don't know why you are bashing the DART heads, also do realize this was their first LT1 head - their other ones they're coming/came out with flow extremely well, and are still priced cheap. You argument holds no purpose in this thread because this wasn't a thread intended to see if ported factory heads can outflow as-cast DART heads, because everyone knows they can. It was just a freakin article I found and I thought I'd share lol. If you don't have the money to buy DART heads, just stick to your factory castings. Sure I could have gotten away with another set of factory heads but I was in a complete rush because the car was my daily and I couldn't find any stock heads anywhere, and Murrays (local speed shop) had these heads in stock at the time.

the results are not impressive, end of story. you can jerk off on them all you want but a set of budget ported stock heads will walk all over them. you found the article and thought you would share, I read the article and felt like sharing my thoughts. isn't sharing fun?

there's a vendor selling brand new dart heads with edelbrock intake for pretty much the same price right now, so I'd hardly consider them "budget" when a brand new casting can be had for the price of port work and assemble imo
with a better selected cam I imagine the power output will be around the same give or take

let me ask you guys something. when you look at old school engine horsepower ratings, do you believe them? thats basically what is being used here. why don't the 1970 370 hp LT1s run with the 345 hp LS1s of a few years ago?

saw a post on camaroz28.com where a guy was running 119-120mph traps with cc306 and stock dart heads, not bad imo for out of the box. magazines are usually fairly conservative with cam selections and other mods imo
the LE package is a good deal tho btw

lol @ captain obvious over here... These heads (especially the 180's from DART) are not supposed to be some badass head. It's like saying... The factory LT1 head doesn't really provide us much flexebility until AI or LE gets ahold of them. It's the same concept. They weren't meant to replace fully ported heads, they are made as a stronger aftermarket casting for people who want to get it ported/worked on further. I don't understand why you are so salt about an off the shelf head, that isn't even ported. The fact that it is STRONGER and will OUTFLOW a FACTORY (untouched head - lets be fair, this one's untouched too) is pretty impressive. I've never seen DART advertise about some "bad-*** LT1 race head that stops the world from turning". It's just another aftermarket casting for further potential porting and such. Get over yourself.
