Hi to All,I would like to get a guesstimate on the appox. crank HP/TQ on my build, here is what I'm putting together.Thanks for any help.



350ci Flat top forged pistons

Bow tie Phase 3 heads 202/160 64cc chamber 184cc intake runner

Comp Cam XFI Camshaft Flat Tappet Hyd, Gross Lift 520in/515ex Dur 224* 231*@.50 w/1.6 rocker 113 lobe sep

Comp Mag roller rockers ratio1.6 comp lifters& pushrods

Lt1 intake conversion

Custom chip

Short Headers true duals no cats

Gut MAF

How do you guys think this combo will run?it is going in a 85 vette with 3.07 rear gear auto trans.Any guesses on idle quality,HP? Thanks again.

 

 

Its going in a 'Vette? BAH!!

Just kidding..

If I were to take a stab at it, you should be running
between 295-300HP at the wheels..maybe.

Its hard to define a build, we have no idea who
tuned it..but, going by instinct its looks solid.

Why flat tappet? I like them, use 'em all the
time. But, for your setup I would have done at
least Hydraulic roller. 'Cause it looks it could be
a high winder.

LSA on the cam is acceptable, 112-114 on
computer controlled stuff is the limit, so your
borderline..

Id say, 303HP/330ft. lbs TQ at the wheels

Best case scenario, of course ..

 

Thanks, i went with a flat tappet cam because my block is non roller and my small buget.

 

If I had to guess, 2. A guess is just what it is, a guess. If you've got the $ to build it, spend some more on a dyno and find out for sure! A dyno print out will be a selling point when you decide to sell it not to mention the bragging rights to your buddies!

 

That is a good idea when it's finished,but I was looking for a appox. HP figure for now,make sence?

 

Yea, its completely understandable to get
a rough estimation of the build's power potential.

I think idle/streetable wise, it'll be stunning.
Ive no prior experiences with a LT1 induction,
but it should make good numbers past 5000rpm.

Flat tappets are a cheap and effective way
to make power and getting your car on the road.
But, If you have roller provisions on the block,
Id suggest going with a nice Comp or Crane
hydraulic roller grind, I just saw you dont.

Stray away from synthetic blend oils &
be generous with the assembly lube if It
hasn't been built yet, Flat tappets like the
conventional stuff.

Good luck

 

Thanks,i'm running shell desiel oil with EOS,I'm almost finished can't wait to fire it up,another couple weeks.
