I am going to build a 427 LS7. I was wondering if my cam that I have now will work with my FI set up? Cam is 244/248...612/615..112+2 LSA. If I use it what will be the goods and the bads with that cam? What cam would be good for this set up? Motor will be around 9.0-9.5 comp (what should the comp be?) and 14psi with the F1A. Cars is a 6spd with 3.73's spool. Any info will help

Pretty much any cam will work with a centrifical blower, ideal is another story.

These cams tend to use boost diffrently vs a traditional blower cam with zero to a few deg of overlap.

I would try it and see what she does, but you are in the ball park for a mild to moderate street cam.

What cam or who makes a good cam for s/c? That cam is in my n/a motor right now. I will get a diff cam if needed. This is a street car so I would like good low but good top end. 850rwhp+

Jake@EPP

Give us a ring tommrow, we can go over some specifics and figure out what would best suit your goals. 850hp wont be much of an issue

That Cam will make a decent Peak hp but not so great midrange.

Wider LSA 114-115 would be better

anybody else? I will call u EPP

Jake@EPP

Sure thing, speak with Dustin. Hes far above my head on specifics in a cam. Be ready for him to ask a ton of questions on your setup lol.

I looked at speed Inc sc4 cam. It is a 234/240.. I think the lift is 58?/59? ..114lsa what do yall think?

Jake@EPP

It all depends on where you want peak hp at?


A 427 will want a larger cam for sure, something in the 240s/250s for max streetable hp.


What cylinder heads are going on this?

Intake design?

Blower / aprox boost (pulley dia).


A smaller 230s/240s cam will peak around the 6k mark and depending on the grind it may carry it on for a little while.



For Example,

Our FI cam (232/240 595/608 115), is a great cam for 346 motors, we see a general peak on average with blowers in the range of 6500-6700 depending on alot of variables.

In a 382 that same cam tends to peak 200 or so rpm less, but usualy with a broader tq range from the CI.

In a 402/408, this cam peaks right at 6000/6100 ish, torque band is broad, but not where it should be.


We now offer a larger 400in cam for this reason, it is a 236/246 60x/60x 114, this is a nice cam that will bring power out to the range of 6400-6600 depending on heads/intake combo.


As allways, a custom cam will be more for your setup then rather a shelf grind. Some heads flow better then others, and a vr jr will spec out diff then a fast 90.

I have a ported FAST 90 with the TEA/TFS 235 heads with kooks LT's with true duels and a X pipe

I would like good mid and good peak. I would like good tq under the curve

Thanks for the info. The TFS heads should be good with FI.

FYI this cam on my n/a set peaks out at 6200-6300rpm. The TFS has good mid power.
