    Another underpowered 307 and badly geared gbody

    Hey guys I guess it's official I am definitely a gbody guy now cause I'm now on my second. It's a 1987 Buick regal. It's just a shame that such great looking cars can be so underpowered. I may try to do some little things over time to increase the power of the 307 but for now I think the best...

    Pushrod length??

    I have an olds 425 (not the toronado motor) that i bought for a swap. It ran good when i bought it on the stand but it wasn't getting oil to the rockers so i looked a little deeper.

After much research i think it looks like the only headers that will fit exactly without any mods cost at...
