To go further is alot of money... just seeing what my options are if / when it sells as to whether to do my HQ... or find something else. Its all just for ideas at this stage, nothing serious.

to run 10's in a hq with a holden engine for 10k,while yes its possible, your gunna have to stinge on good parts.. and stick with cheaper stuff - and lose reliability. Realisticly, 530-550hp is going to be the goal, and making that much power on pump fuel is really stretching it, and certainlly wont be done for the budget you have. Step up to Avgas or methanol and it becomes a bit easier, and you might just get there with the money you have to spend. Its going to need to be a stroker... so theres 1200 for a crank Heads are going to have to be VERY VERY decent, and will need 2.02 and 1.6 Valves, and a ****eload of port work... bye bye best part of 3k. That sort of power is going to need revs... and prolly up wards of 7000rpm. So the bottom end will need to be up to the task, studded and H-beams at the very least. You'll get away with ACL Race series pistons, and a rebuild kit can be had for 700 odd inc a set of pistons/rings. Intake/Carb etc is gunna aorund the 2k mark..' As you can see, the money dries up quite quickly..... Add some gas into the equasion, and it might become a bit easier, and allow for you 3000rpm convertor and tallish gears... you'll get back some drivebility also.

And i like my stock Fuel economy... so.. i bought a turbo Some original photos have not been recovered yet.

sinister.. lpg falcons in the 10's yes... with turbo's that makes boost alot earlier then a blower... When i said economy i meant in regards to convertors and short diff gears etc. Haddad's HQ had a small cam? From memory it was a Crane 272 Solid wasnt it? Not exactly Small. Not to mention the amount of boost they were screwing in, and or the convertor and gears being used.

How many small block HQ's do you see in the 11s? That are street driven? id hazzard prolly 1 in 100 of em..

not sure how it was setup on the hq, when it was in the vl i got the specs right here 3.7 gears, 3600 converter, 12psi from the s-trim, 674hp @ 6200rpm. 10.56 @ 129mph on "street slicks" cam is a hydraulic but it doesnt say the specs, its def small, ive been right next to the car and like i said b4 its the biggest sleeper going around, u cant even hear the blower or have a clue the motor has any unsual GO until the pedal is smashed

sorry mate, i dont believe that for a second. Too Start with a Strim would not even go close to making 670HP, and especially with 12psi of boost. A Trim, yes, i would believe. Im not guessing either, ive got a fair bit of experience with vortech blowers... Its just no possible. Sorry. 550hp would be max, perhaps 580. As far as the cam lump, you wouldnt pick what cam is in it, that the beuty of blowers, the make a lumpy cam smooth.

It is illegal to use gas on the street but it only really matters what happens at the track. Run a 10sec pass on the street and get caught your ****ed whether u use gas/turbo/blower to do it. So if gas is cheating,being a form of forced induction i guess turbos and blowers are cheating also. Maybe we all better go back to running n/a hey?

I think that he and I meant that nitrous is like an additive and you cant run it on the street. a 'true' ten second street car isnt exactly that if it reels off a 12 without nitrous.

Sinister; you say 6/71's are outdated, would you say the same about their big brothers? ie; 14/71's used on Supercharged Outlaws.
