Should I drop some BBR cams in my turbo 326?

[US-1]

The cams won't be the limiting factor in rpm. The stroke will be. Those bigger stroke engines don't like going over 7000 rpm for very long. Plus....you won't have to twist the engine past 7k anyway. That thing is going to make absolutely stupid power up to that point. I really see no reason to spin that big bastard over 7000 rpm.

If they can change the LSA with a one week turnaround I would go ahead and order them.

Yeah - that's what adam was saying with the big stroke. He was saying I'll most likely be shifting at 6K and 6500 max.

I think I am just going to order those on Monday with the 14 lsa. It might not be the perfect 227/237 but it's pretty close and conveneint 1 week turnaround with the lsa change.

I'm probably ordering them on monday but do you really think they will give me that much more accross the board? Basically, in your opinion, think they are worth it for my car?

 

[US-1]

Yup.

Please tell me, what is the effect of reducing the lsa to 114 -vs- 115.5?

 

[US-1]

This will narrow the "window" between the intake and exhaust centerlines. If the exhaust closes too early the scavenging will not be complete and the incoming charge will be contaminated.

Generally, tighter lobe separation angles cause an engine to produce more midrange torque and high rpm power, and be more responsive, while wider lobe separation angles result in broader torque, improved idle characteristics, and more peak horsepower.

This is just a guideline of course. Very small cubic inch engines need a very wide lsa. Smaller stroke engines for example. With these big bore, stroker engines I honestly feel that anything wider than 114 degrees is not needed. If this were a stock bore pushrod 302 with a stock 3.00" stroke the 115.5 or 116 lsa would work fine.

It looks like I found this thread a little late. I would have snatched up those BBRs too. Does anyone have an opinion or experience on the BBR turbo grinds that they offer?

I have not seen any turbo-specific grinds on their site. Do you have any numbers on these cams?

 

[Turbotungsten]

No numbers as they wont tell. What a secret! Thanks for the warm welcome!

 

[canuck power]

I may have to phone Chris on monday
