might as well ask the guys that know these things, is this cam tunable for tbi or is it to large?, not using ebl just 7747

Depends on the experience of the tuner. Yes it seems tune-able to me. Whether or not you can do it, I have no clue.

Why so much cam?

 

ok cool just wanted to know, i didnt want the cam to be so radical it wasnt tunable, but im confident i can tune it, the last one i did wasnt as bad as i thought it would be, the only hard part was getting it to idle without surging, i figure if im going to build an engine might as well do i right and put a somewhat large cam in it

 

FAST: when is "lift" an issue with stock heads and rockers? int .489/ext .504

 

I guess I took it for granted that he would know the standard small block lift limitation for stock springs. TBI heads are no different than any other small block heads. You can go .480 cautiously on most heads.

This is a much better cam for a swirl port build in a TBI truck. I am assuming that this is going in a truck 350.

Keep in mind that this cam has 62* of overlap when measured seat to seat. It will reduce idle vacuum, have a rougher idle, and be more difficult to tune than a cam with less overlap. But it will still be "easier" than the one that you specd earlier. They sould like the old LT1/L82 350 engines when you have them tuned well. It is an instant muscle car era throwback when you get it tuned well.

You can get the complete cam kit with valve springs and retainers fro $252.99 from Jegs. Part number 270-110172, I have used it successfully in several TBI builds, I would recomeend it over the L82 cam that I ran for a while in my 305.

I had one in an otherwise stock 350 and picked up 17 RWHP/20 RWTQ over the factory "929" cam.

I did two DD2000 simulations with the stock 193 castings, cast iron manifolds (headers on #2), ultimate TBI moded TBI, 9.5:1 compression, and good tuning. The only difference between the lower two is headers and a good exhaust.

Eventually I will end up with this cam and a 2,500 converter in the 1991 G20 that I picked up recently.

 

i have s/r torquer heads so hopefully lift wont be an issue , have two other question, i was told that i might have get shorter pushrods for this cam because valve geometry will be off?
the other is will stock 55lb injectors a 20 psi support that cam with those heads?

, thanks

 

my friend is an engine builder. he takes nothing for granted. he validates the geometry and measures carefully. then uses the appropriate size.
