What does it take to reach 500 ftlbs N/A? I'm gonna assume it takes cubes... What's the best way to get there and can this be done and it be streetable? Say a 90% street car? Full A/C, interior, driveability, ect?i know everybody is obsessed with HP but I want a snarling mean street beast that sets off every car alarm in a 10 mile radius, while pulling freight trains off the tracks?

Lastly can it be done around $10,000?

Depends what you are starting with my 383 ls1 stroker got close to it "486lbs" with afr 205 and a 23? in 24? ex cam with the stock ls6 intake and stock tb with a cd stalled a4 and stock 3.23 gears

BigE_LS1

Heads were milled to 59cc to up the comp. . I am now looking to get even more with my 402

A small shot of nitrous will do it

BigE_LS1

yeah that another way to get there lol

Lol. Yeah a little laughing gas will make her talk I'm sure..... I was looking for a more direct approach. Assuming I started with no engine... Buy a LSx crate motor or build one? How many cubes does it take to be streetable and hit 500 without leaning on the ragged edge of reliability?

I'm proud to say I have all of the above....and at the same time sad to say $10,000 won't buy the top half

Ewwww so what was your recipe? And how much lighter a wallet does it take?

BigE_LS1

You can do it with a 383 hell its been done with a 346 a few times , but the more cubes you have the easier it will be for you. Also the bigger the cubes the more the motor will be able to handle the bigger cams and still be easy on the street. Now saying that I will say it will come down to your heads and intake sys. Heads are the hart to the motor . The better the heads the more power you will make . You cant just throw the biggest cam out there in it and not have everything else match it . Get the best heads you can afford on it and have a good intake sys match up for the heads. Then have a custom cam spec out to match the flow # that your heads have and I cant stress how important it is to have the cam spec to match your heads flow #s and were it flows at and at what lift. Just take your time and do your research man there are lots of people in here that can answer just about any ? that you may have .

Link in my sig....

But the readers digest version is, 460", big Mast heads, big hydraulic cam and 8 little throttle bodies

You shouldn't have a problem getting 500ft-lbs with a 402 or larger. I'd be willing to be you could even do it with ported OEM heads and a FAST intake.

Stroker and comoression, lots of torque and 500 torque isnt a streetabilty issue, high n/a HP with Ron Jeremy cams is what loses drivability, small cams and big cams torque gain isn't huge but they gain high rpm power. Also e85 if you can run it will make this MUCH easier. I gained 31ftlbs from that alone. Hence my mild 10.7:1 5.3headed 346 LS1 with a 232/236 cam made 447/428, thats a lot of torque compared to my hp number

I'd like to build a 427, so maybe find a shortblock, drop some good heads on it with matching cam and this shouldn't be to hard to hit?

Cakewalk. LS7 heads wouldn't have any problems with 427ci under it. How would you want to build the 427? 4.125" bore and 4.00" stroke or 4.070" bore and 4.100" stroke?

Why 500? Why not a track time?

StreetGliderX

iTrader: (2)

Reason I don't shoot for track times is I'm not a track star I'm a street cruising smack talker. I like the fun factor. I had a Ram SRT-10 that put down 525/536 and it was a blast to drive. Traction never happened but I liked the fun I had in it. You can't hold those kinda numbers on the street really. Unless I tub the car run drag radials among other things. I just like the sound of 427 and 500. As far as what bore and stroke to build at I would assume longer stroke would yield the better tq numbers. But i am open to suggestions. Is there a decent crate engine that a man can buy and make it fairly simple swap and tune?

So how bout offering some advice as to what I should build instead of getting bent about me not wanting to track my car daily? If I can build a motor with a TQ curve that looks like Jed Clampets kitchen table then it should be a potent street car.

Without a fast intake you can get close price wise but you need one to hit your number. I spent a bit more getting coatings on the pistons etc. The dyno sheet I have is with a 90/90 setup and if I remember correctly the motor hit 485 ft lbs at 3200 rpm and just pushed up from there. That is with an off the shelf comp cam with no more then .610 of lift. The tuner, Arun who does a lot of FI cars was pretty impressed that the torque curve looked like a table top. Just remember you are going to have to spend about half as much again on the drivetrain because it is going to want just shred itself to bits. IE the ls7 clutch that lasted 3 passes at the track. Also twisting the 5/6th gear shaft.

Sounds like a solid setup you got man. I already ordering a S60 and I was planning on some more upgrades. I would just like a nice flat tq curve and a potent play toy.

Anything 400ci and good parts .... No ported 241 heads or 243 bull, you need good flowing heads and a decent sized cam .... My car tools around at 1300 rpm in 4th in stop and go traffic no drivablilty issues.... Also has a lot to do with tuning for drivability .
