Ok I know this is speculation but I plugged in all the specs of the cam a guy is selling me, Comp Cam 230/236 110 LSA 544/555 with 1.6s.
I have the specs on the cam card and plugged all that into the desktop dyno with AFR 210 heads. 11 to 1 compression. and Large tube headers without mufflers and I got.
509 FT/LBs at 3500 RPM
501 HP at 6000 RPM
That is Flywheel horses.
Does this sound right?
This is the engine I am going to build and would be very happy if it makes this much power.
I have the file saved so if you need to know anything else let me know.

Not sure about the heads or if AFR even makes the 210 for LT1 but I got the flow numbers from the Sept 2000 GMHTP and plugged them into the Desktop dyno.

 

Sounds pretty close....that's just a bit over 400 at the wheels. I think that may be a bit high but not off by too much.

 

A lil high IMO. Maybe for a 383. On a 355 I'd put you around 380-400 rwhp, 410 with a good tune

 

Anyone have any input on this?
I can,t justify the extra cash to build any stroker if a 355 is gonna push this kinda power.

 

if the AFRs are well ported, and the cam is matched............you can get 450ish at the wheels.

 

Thats about right, I have 480 flywheel out of my 355 dyno proven.

Q

 

put stock lt4s on the desktop dyno, its like 5hp less

where can i get desktop dyno???

 

Any speedshop should have it,
If I were you I would search on Kazaa cause I bet you could download it for free.
I bought mine at autozone.
