    how to make a 6.1 spin safely 7500 rpms?

    Yes i understand, i come from a LA background and was about to put a 418 cube combo together but after wanting a more powerful combo (over 600hp) it became aparent the G3 is a better option. Example best 340 head flows 200cfm Well ported W2s 320fm Indy heads 340cfm Std G3 6.4 heads 340 cfm and...

    how to make a 6.1 spin safely 7500 rpms?

    A std 340 with cam, intake and headers aint ever gonna see 425 hp without thorogh rebuild and quality components. Apply the same theory to the G3 A std 6.1 with cam and headers will make 450hp and a 6.4 over 500hp. The.engines are different era's and the quality factory machining and casting...

    how to make a 6.1 spin safely 7500 rpms?

    340 is good for boat anchor as they make 120hp less than a 6.1 as they left the factory. How many passes would a stock 340 have lasted at 425hp? Its 2017 now not 1973 Anyway valvetrain is fine to 7500rpm if looking at the dragpak cars is anything to go by.....8000rpm onstock rockers

    how to make a 6.1 spin safely 7500 rpms?

    The real weak points are the cast pistons, powdered rods and the oil system. Aftermarket pistons and rods are readily available and make sure u have a healthy oil pump, a large enough sump and use the correct weight oil for your specific oil clearances

    I'm dying here

    Missed on this combo?

    I don't think Ironmikes heads are the big mouths just the full cnc standard port, hence why he doesn't have offset rockers

    Missed on this combo?

    Man i hope you run the 2 heads back to back. I think you will sell Rods heads for him after that

    408 small block street build

    A few posts back he stated he has already paid $3200 for custom headers. Lots of 10 sec cars here with 1 3/4 pipes

    408 small block street build

    Missed on this combo?

    Missed on this combo?

    I would love to buy them for Ironmike to trial as im close to pulling the trigger on some but im on the other side of the world so its a bit tricky

    Missed on this combo?

    I like this thread. IronMike I really think you should bite the bullet and fit the BPE heads and see the difference. I think Hughes stuff is inflated and over advertised for what they are, no offence to them

    The everyman's 360 LA Eddy headed engine dyno tested

    I agree, my own 318 engine dynoed at 411 hp, in a 3525lb car went everything from 13.1@111 to 12.3@111 depending on gears, converter and chassis set up thrown at it

    371 build W/Big Mouth heads

    Not to discredit hughes good work but ive seen their 300 cfm stg 3 Eddies only go 280 on someone elses bench, and their 700+hp G3 hemi is unbelievable literally

    ATTENTION 318 owners: any interest???

    416 Upgrade

    I dare say your builders bench is flowi g at 25 or something as they flow more than 220@.5 before Brian touches them
  23. L4staero

    Gotta get this sorted out!

    Sounds like its running out of fuel supply. Check between pump and carb inlet for restrictions, restrictions from tank to pump, blocked pick up, blocked filters.
