Hey guys...I'm looking at a nitrous cam and was hoping for an opinion or 2 in regards to streetability. I'm not the most knowledgeable when it coma down to these choices and need a little help. This engine will primarily see the strip but I would like to go grab smokes and the occasional jug of milk from time to time! Am I out to lunch here?

Can you tell us more info about what is in your engine for parts and what you have for gearing, trans type, tires, and chassis work?

It's a stock windsor based 72 block, 393ci, scat crank, eagle H beams, JE pistons, AFR 225's, Super victor intake, and full canton bottom end including girdle. The rear end is slightly built, moser 31's, C clip elims, 410's, full spool. Rear end of chassis is mini tubbed. Fuel cell and battery reside in the back, running QA1 coil overs. Tires are 28x11.5x15. I'm going to run a C6 built by Frank Merkyl. Hope this helps...

Just a few more questions, what compression are you at and stall converter size? Sounds like a great play toy to go have fun with. :supz:

I don't have a converter picked yet, I planned on basing it off dyne sheets to see where exactly I build power and torque. Compression sits at 12.5:1...hope this paints a little bit more clear of a picture!

I personally think that it is a little large on duration for my taste. This cam is more along the lines of what I think would work better for your given engine combo for a off of the shelf cam, http://www.cranecams.com/product/cart.php?m=product_detail&p=24743 .

290/294 @.020"
258/262 @.050"
178/182 @.200"
.672"/.672" w/1.6 rockers
110 LSA
105 ICL

Personally I would go with a custom grind cam like this one:

288/298 @.020"
258/266 @.050"
182/185 @.200"
.715"/.701" w/1.6 rockers
.012"/.020" lash
111 LSA/107 ICL if you are spraying a 175-225 shot

IMO those are some big heads and intake for a 393.
You might be reading it wrong, I was too and it was pointed out to me the OP made a remark that is confusing

The original poster put down for cubic inch "Volume 351" and I took it as this thing had a runner volume of 351cc's, then it was point out in a later post it is a 351W with AFR225 heads and IMO AFR225 is not too big for a solid roller 351W he is going to spray here and there, which is probably a 150hp shot but this is just an assumption on the HP shot, but the head volume got me also until I seen it was a mistake

The OP has a stock 1972 351W block that has been stroked to make a 393 cid (4" bore x 3.9" stroke). An AFR 225cc intake runner head is not that big imo and in fact kinda on the small side for a strip (mainly) car. If you were to talk with Brian Tooley at Trick Flow I bet he would tell you that he would have you useing a 240cc head. I have used the AFR 225cc heads on aggresive pump gas 347 cid builds before and they work extremely well with a single plain intake and nitrous. IMO when he is on the spray he needs a bigger head for the engine.
