It's been a while, but one engine went into a challenger I believe, in Az and went 9.90...full bodied car so probably around 3500lbs. or so.We don’t know if something is an underachiever unless we know what it runs and weighs, and what the combo is though, do we.
I have nothing against Brian, by all accounts he runs a nice shop.
As a business owner myself, it’s good business to sell the sizzle. Like I said, knowing how stuff ultimately runs says a lot about the validity of the numbers.
For my part, I am not gonna assume the two guys with the 650 horse heads put them on doggy running combos without track numbers And or more information than just saying they made 650 horsepower.
As I mentioned earlier, I wasn’t upset to hear that heads I was proud of and ran good (W5) didn’t break 300 on two very,very respected benches.
Numbers, I have found by personal experience, don’t mean ****. it didn’t embarrass me, it was just reality. Is what it is.
The other went into a Dart, I believe in Colorado so I'm pretty sure it's raced at Bandimere...that engine had nitrous put on, but before that he ran a best of I think 10.50's, maybe a 10.40 something before the nos...with nos it's gone 9.70's.
When I built Mopar Billy's engine (on Moparts) we used the AirWolf heads, 11:1, solid FT cam, 410cid, and that made 606Hp on my dyno 4 times in a row...so well ported TA heads with a roller cam and 13:1 making 650+HP seems legit to me...cars ran good, but I've done some other engines with Indy heads, high compression, etc...that made 700HP and the cars were all over the place...all because of poor chassis/converter setups. I don't have time slips, you don't have to believe a word I say...I was merely trying to show that the TA head seems to be an easier way to get more power than plugging the pushrod holes in an eddy head and moving them over for more power/rpm.
They also come setup for BB mopar rockers (more ratio available using TD rockers), 3/8 bolt holes for the shafts, 5/16 stem guides and valves, and OOTB they flow on my bench about 260-265 cfm which is a great starting point for the DIY porters out there.
