What would be the minimum required to spin to a max of 7k safely? Trying to decide on my build direction and need to find my build limitations since I’m new at this. Want to spin it to max 7k to get as much hp as I can without having to move into the car. It’s going In a street/strip 70 javelin 5 speed.

I'd say for long term reliability, you probably need forged pistons and rods, but you would be able to turn 7K on factory parts if the valve train is up to it.

Forged rods and a way to keep oil in the pan at all times would be my first two boxes to check off. I would think a properly prepared (cast) 360 crank would be ok at 7000, but I bet the whole thing would appreciate 6500 a lot more. |

I don't think 7,000 rpms correlates as a street/ strip engine. If you truly want an engine that will still be making power at 7,000 rpms it will not be a very streetable combination. Either way you need to plan on spending some serious money for reliability at that rpm level. Nothing can be over looked or skimped on.

Tom, the dream is to have it rev to somewhere like 6,500/6,800 and me being a pessimist want to ensure if I I slip up and don’t shift until 7k I’m not gonna be left pushing it.

I'm running reconditioned factory cast rods with ARP bolts and cast pistons in my 360, got 30 passes on it now turning 6300-6400 but it's been up to 6700 once or twice already, wish me luck

Can add nothing from real world hands on experience, but would say from reading
agree with other poster, keeping oil in the Pan for the pick-up, aka adequate drain-back, like the AN lines a forum member posted pictures of they added to the heads at the ends rather than attaching them to the Valve covers. It is a lot of reading and you will have to create a log-in account to see the pictures, but there is a LOT of good AMC Traco Info posted over on the Camaro Research Group CRG Forum under Trans Am Camaros under Traco Fans...

With a good valve train & ignition almost any motor will rev that high but..... In order to need to rev that high you'll need a few more things than a good short block. You'll need a cam, intake & heads that will support that kind of rpm or you will just be making noise & probably be slower than if you shifted lower. A good motor is achieved from a good combination. More food for thought.

Why spin it like that? Everybody wants a $10K+ race motor for the street that never gets built. Build something realistic and go drive it instead of sitting around dreaming of being a hero.
