Somewhere between 250 and 300 would be my wild crazy guess.

Compression is probably a tad low. It will be a decent street car but for drags you do not have enough cam and then you have to add gears and stall if its an automatic.

Please do explain on yer junk heads.... And the reason for Hottarods low WAG is there are still to many unknowns to your build. I woulda guessed a tad higher but not by much... :)

Lol, ok on the heads, they came preassembled with chinese junk. It was idling in the front yard one day, and a keeper popped off a valve, shaved a cam lobe, and just generally had a piss party in my motor. The valve in question was not machined correctly on the stem groove. To the other questions It has KB hyper flat tops, A TCI streetfighter c-4, with a 2800 stall. Will be going in with a Ford 9 in. soon. The car is not meant to be a Full race car anyway, The random trip to the 1/8th mile track here. but mostly daily driver.
Also didn't mention on the specs the cam has a 310 duration.

Well I for one am a closet Maverick guy (my first car was a $99 dollar 71 Mav) ANd I hope that the Chinese crap stops failing on you and that motor spits out a whopping number of HP for you :)

Lol thanks FE, I love the car, not because of its past, but simply because it was the first car I ever owned and drove. Sentimental if ya will. Anyway Thanks for the replies. No more cutting corners for me, I learned my lesson about buying parts that are cheaper. Quality all the way.

I love the Mavericks too. My first car was a 1970 Maverick grabber in grabber blue. I wish I still had it.

What is your horsepower or strip et goal for this car? It would be easier to tell you what it will take to get that.

I guess around 300 to 325hp... I think with that amount of power in a light car(2500 lbs) It will move pretty good when ya want it to. Don't really know about an ET. I know 12 secs is as hard to hit as the speed of sound on a jet per say. In other words its a feat within itself, lol but im not gonna be running 12 sec 1/4's. We have a 1/8 mile track here, that I may run a few times just for the fun of it.

I ran 13.31 best with ported early 302 heads(shaved to 55 cc's), Performer RPM cam, RPM intake and 600 vacuum secondary carb, 4.10 gears, 3000 stall, tri-y headers, 8 1/2" slicks. My car had not been gutted so with me and fuel my weigh in was around 2950. .030 over 289.

set a goal first then build/change from there.

if your just looking for 12,s then the engine setup is probably close.

drag radials,gear in the rear and a good converter and you should be there.i am sure probably needs some tuning carb wise and timing curve and so forth.

That describes mine. January will make 40 years that I've owned it.
