The motor is a 383,aluminum Corvette heads ported and polished they flow very well for what they are..it has an lpe219 cam a First performance intake and for now it has 1-5/8 edelbrock headers, custom 2.5 in ypipe,into a 3 inch high flow cat into a 4.5 inch mufflex exhaust car is going to be using a Holley efi terminator x system curious on what it will make hp wise.

 

More than a underrated 305, but less than a Death Star™. Hey, you said guess...

 

Lol I know it's an old build meaning it's been done before.

 

I guess 1.21 gigawatts.
Since 1 HP = 746 watts,
Then, 1.21e+9 / 746 = 1 622 636.73 horsepower, provided you reach 88 mph.

Seriously, good combo you have there and getting rid of the exhaust restrictions will help greatly.

 

Trouble with estimating is that it's still just a guess. You can hope to make a certain level of performance, but that's your goal, you won't know what it really makes until you can accurately measure the performance. Even then, you can't really equate your measurement of performance to someone else's measurement from across the country. Build two engines as exactly the same as possible, you still might have one that makes it through the break-in with a more magical set of wear marks, or one might wipe a few thou more or less off the camshaft. Any number suggested or shared is subject to a "prove it" anyway. Without the Certificate of Authentic Performance (time slip, dyno sheet, etc) you might as well be asking Big Cletus about the 'widda-maker' under the hood of his "Big Rhonduh!" It's all just a tall tale.

 

Thank you im.hoping it runs good!!

 

I understand that just was looking for an idea being it's a build that's been done before.

 

Found one for you: https://www.thirdgen.org/forums/alte...afr-195-a.html

 

Dont know what hp it has 1st few passes out it went 12.3s at 109.8 mph with 1.6x 60fts

 

350-400

 

I'd take that..want to get this in the high 11s on motor

 

I guessed at the weight. I'm at 3650 (w/200 lb driver), iron heads, glass hood, SFCs, full interior. Figured you should be close although with aluminium heads (and a lightweight driver).

 

Not bad considering its nothing crazy ..

Hoping To get 11.99 next time out.. we are like 0.38 tenths away ..lol

 

That's a strong running streetcar. I figured about what you are seeing there, I bet cooler weather you can get it to 11.9xs

 

Thank you..its pretty respectable considering it's full weight still has AC too...our goal is to get it to run high 11s then were putting an old school paxton on it.. were waiting on paradise wheels to make the vr4 kit so this can be upgraded to that style.
