hi
how much hp do you think my motor will make
It is a 84 305H.O
with 1 5/8 heddman headers,
weland action plus intake manifold,
700cfm 4 bl carb.
and a mild street camshaft
287 287 214 214 . 444 .444 107 117
so how much hp will my motor make
THANKS

 

Is 117 the LSA??? WOW!!!

I thought my cam with 112 was a lot. I hope that's a typo on your part.

Using 117..... DD2000 says 225-250 HP and right around 300 ft-lbs. of TQ. But there's too many other variables involved.

What exhaust are you running after the headers? Are you using stock heads?

 

i think he means
107 intake centerline,
117 exhuast centerline
which would work out to a lsa of 112 with 63 deg of overlap
using 287 and 287

 

is it is lobe center line
int. 107 ex. 117

i got the numbers on a web site

 

Where's my sign???

Well let me redo the numbers then.

Here's a pick of the two.. one with High Performance exhaust manifolds, and one with "headers and mufflers".... I'd lean more toward the HP manifold numbers since DD2000 is known to be a little optimistic on torque numbers.

 

I think on most applications DD2000 over estimates. But those numbers look fairly reasonable at the flywheel. I would have guessed around 230- 240 at the flywheel, but heck thats just my opinion, and opinions are like aholes, everyone has one. But I think thats close.

 

thanks
the motor got headers like i said and 3 inch exhaust with no cat
