So Im new to this forum! Hi guys! So I own a 1969 Oldsmobile Toronado with a 455 front wheel drive with a Th425 3speed trans completely stock numbers matching and about 95k miles, I also live in Denver, Co... It's my first classic and I'm stoked... Now I know with this car I'm limited on what I can do with out blowing endless amounts of time and money. I'd love to see her hit 1k hp and 1k ft-lbs but I've herd roumors about steering and traction becoming a big issue on this car when built up... So all and all I still wanna get up as high as I can... And still be useable... She's also a daily... Well first off I'm trying to decide on a carb I've dismantled and rebuilt 2 "750" Qjets tuned them and modified them and she's just not doin what I know a 455 with Toro heads can do... So For arguments I know most suggest Qjets but I'm looking at Holley I've been eyeballing the 770 aavengerbut ran across a 750 quick fuel Holley vacuum secondary rebuilt for half the cost I've done some research and they look quite similar from reviews... My question is have you ran either on a 455? Which feels better? Opinions? Also... I've called both comp cams and lunati 10x each and still can't decide on a cam... And each time I call them they suggest something else... What's works best for yours? I want max street and driveability and nasty lope but still useing power breaks?... And my lastly... I'm planning to eventually do an over haul on the engine... Forged internals, oil restrictors, port match intake and exhaust, deburr the oil return, possibly over bore it .40, New bearings and all the fun stuff... Possibly boil the block to ensure all water jackets are clean... I'm debating on an intake manifold and I know I'm limited due to hood Clearance so go big or go home right? I'm debating on a high rise intake and do a scoop on the hood or a tunnel ram with a single carb and a butterfly scoop... I know tunnels are great for style... But with long straight runners... Wouldn't bottom end tq bump up? Either way still would like opinions!! thanks guys for your future advice and opinions!

 

Welcome to the site, sounds like an interesting project. Post some pictures when you get a chance.

 

Seriously??

 

Here ya go these were taken when I bought her.... NO cancer just surface rust... I do paint and body work as well...

 

Yes really!?! I see hardcore hp cars used daily why no mine? I know gas is a pain but you know test and see... Compression isn't a huge deal here since I'm at 5280ft above sea level... It kind of equalizes...

 

I think Jay Leno has 1,000 hp in his Toronado but look what it is. I can't imagine 1,000 hp and front wheel drive. Good luck and keep us informed.

 

If you're serious, you need to contact a known Olds engine specialist, discuss your goals and go from there.

Good luck.

 

Well I was listing my intended goals... But my question remains the same... 770 avenger vs 750 quick fuel, high rise intake vs tunnel ram, and I can't make my mind up on a cam set so suggestions please!!!
