I have a '67 MGB, and when the engine or gearbox goes, I plan to put in a 60° 3.4L L32 V6 from a '93-95 Camaro (because it's a bolt-in fit like it was made for the car).

Stock power (200ftlb/160hp) is plenty, but I fear the delivery doesn't quite suit the character of the car. I would gladly trade torque down low for power up top, and I would really like to get it to rev high just for the fun of it.

If I were willing to get down to the crank and build from there, could I get one of these to make power past 6k RPM and hold together for 100k miles without coming out of the car? If not, is there a way to get a bit more up top if I'm willing to sacrifice down low without sacrificing longevity/reliability? I'm wondering if anyone has done anything similar.

 

The FAQ suggests that this is attainable by pulling the heads, rockers, and intake from a 3400 for use on the 3.4L...

Are there greater implications there than listed? Seems like maybe the compression would increase such that you'd want to change cylinders...? I'm not looking to build a race motor, I'm looking for something that is calm for the street, but is thrilled to run around mountain and canyon roads at high RPM.

Forced induction is out. It reduces responsiveness and engine braking enough that it just makes a car like this less fun; less sharp.

 

if you haven't found yet here is a writeup done a while back, https://www.camarozone.com/forum/f16...stions-178443/

 

Interesting, thanks!

 

You know that the 2012 Camaro 90 deg V6 is rated for 325 HP and was made for a lot of years. You are going to pay a little more for the engine but at least you find something with decent miles that is not 25 years old motor in need of a 5k rebuild. Plus you will be able to find parts. Since the 3.4 only was made 3 years and was only in Camaros you are going see support for that motor all but disappear. There are a lot of "Looking for parts" post in this forum.

 

Yep, but the 90° V6 doesn't fit in an MGB without lots of fabrication, whereas the 60° V6 bolts straight in.

 

That is my bad, it is a 60 degree, I knew that just typed it wrong. It also rated at 7200 RPMs. I know the top is wider due to dual overhead cams but I would guess the bottom would be close to the same.
