Cam spec

[peter.farina]

I just ordered a .581 lift 235/241 duration 112,LSA. Cam for a 351w stroker 408 using 210 cc promax heads and a supervic efi intake what should my turn out be on manners and power

Good question.







I'll leave the desktop dyno estimate alone, but with a 112 LSA it should have pretty decent manners as long as your PTV clearances are good. I have a 112* LSA cam in the 302 in my Cobra with comparable lift numbers, although the duration numbers are a little shy of what you're saying. It's a pretty mild cam, made for trucks and RVs.




I lied, I'll take a shot at your power numbers.... I'll guess somewhere in the 425-450 HP area. My 302 puts down 265 at the wheels, so I'd estimate that it'd be somewhere in the 300 HP area. With more duration I'd suspect that your 408 should put out a little more power per cubic inch.

I'm thinking between 550 to 600 hp

At minimum it's gonna make over 500 np it's 210cc heads with 2.080 valves 10.9 compression

Cool! I hope you're closer than my guess! Post up dyno results when you get them!

I'm sure others may chime in at some point as well, I'm sure my estimate is most likely low.

Yea eventually I'm gonna to get it fined tuned I got a terminator x to just get it running I had chose a mild cam earlier and guys were saying at least 500 to 550

Was scrolling through YouTube and ran across LMR's video comparing 3 different engine swapped cars. Their Dragula car is a 393 that looks more similar to your build than mine is. Here's what they put out for info:

Maybe this'll give you a better estimate.

I would classify that cam as on the high side of mild for a 408 cid engine.

How did it go? I m building a very similar build
