dirt track motor

[chevyiiguy]

I was looking at a 250 inline for my 67 chevy ii it was from a racecar that used to race the dirt track at grandview raceway in pa. My question is would a race motor be streetable and what gears I should run I am keeping the powerglide with this set up. Thanks

It would mainly depend on what you may call street able. But anyway It will also depend on the compression the motor was built with along with the size of the cam. The 250 I had in my 64SS chevyII had over 11-1 compression and a cam with a 583-607 lift to me it was fine But to most it would not have been. See my point.
So more info on your motor is really needed to better help you.

Ok I just picked up my motor finally. I am still waiting for the build sheet but it was run on allcohol. It was dynoed at 525hp and has 12:1 compression. It also has a clifford 4barrel intake some major head work .020intake and .022 exhaust
(Maybe I'm backwards with that) but my question now is can I run the alcohol fuel pump with gas? And if the motor was run with a 650 carb would I run the same size with gas. Thanks for any info

[Larry/aka Twisted6]

Just rejet the carb with smaler jets. When running elky you need more jetting because it needs twice as much then gas.

[chevyiiguy]

Would it cause a lot of problems if I ran the elky fuel pump or would it be to much fuel

[Larry/aka Twisted6]

That i do not know for sure,But you could install a pressure reg.

Thanks for all the info

I have another question about this motor, i have a fluid dampener and i need to find a crank and water pump pulley can i use a set off a small block with the short water pump ive seen them at summit for like 60 bucks and thats all i need to drive my car (i think) But i just cant figure out if they will bolt up. What do you guys use?

I beleave i made a post to you on steve's site. If you wish to send me a Email I can Email you some other photo's as to what I did. and The pulley i used & one I had made as well.

[chevyiiguy]

I got my motor running and it runs good I have water methanol injection so I can run pump gas. But I noticed when I pulled the intake off that the intake port has been polished but the head bolt still runs thru it. My question is would a lump port kit help or could it cost me power

[Larry/aka Twisted6]

No it would not cost you power. For the most part it will improve your air flow and gain you some power.

[chevyiiguy]

About how much does that kind of porting cost to do with the lumps and all? I want to get it done I just need to tell the boss how much of the house money I need for my car.

[Larry/aka Twisted6]

I dropped you a E-mail in regards to this matter.

[chevyiiguy]

i broke it! i think i spun a bearing. i overheated really bad it hit 250* and ever since it has a bad knock to it. but im gonna try to rebuild it myself is there anything i should look for and replace? and if its just a spun bearing do i need to get any machine work done? thanks for the info

[Larry/aka Twisted6]

I would check all the bearings ,wrist pins,And the cam gear Esp. if it wasn't bolted on to the cam. If it was alum cam gear and it was not heated before it was installed onto the cam It may have and no dout walked off the end of the cam.ANd if this be the case I'd also check all lifters and the cam bearings as well. Let us know what you find out after you open it up.
