Re: Fuel pump questions (big block street car)

For a quiet equivalent to a Holley blue I use a Mallory 110. The best option for you in my opinion.

Re: Too much oil in sump

Several class racers (NHRA Stock/Super Stock) will drain a quart or so, or put in less than normal amount of their favorite super lightweight oil for a heads up run or for qualifying. They usually have done alot of measuring and mock up on the engine stand to determine exactly how much oil to keep t...

Re: 400 SBC build

At your intended hp level a 383 with a factory 350 block will get you there. No need to go searching for a 400 block.

Re: NHRA STOCK valve job

Yes, any angles are allowed. Also any valve style, tulip, nail head... etc... lots of testing... and different manufacturers valves will be better than others.... also keep an eye on the weight of the valve train components... every little bit pays off big in class racing

Re: NHRA STOCK valve job

You get to do lots of R&D to determine what valves and angles will yield the best results. Lots of flow bench testing to get results. Basically no modification to the ports, no grinding, no sandblasting, no nothing... Each head design is unique and wants different things. What combination is it?

Re: Torque peak SBC

Contact a good converter company, give them your specs and they will get you pretty close. I have used Dice Converters in California - Jeff Paradise, he is a good guy and knows his stuff.

Re: Low hanging fruit.

The low hanging fruit is the converter, gear and headers. I think with a custom spec 8" converter and more gear you would get pretty close.... but you say those are not up for change. Well if it's just for the sake of saying it ran 10.?? Why not just put a small nitrous kit in it. Otherwise put some...

Re: Hyd Roller SBC bracket drag car

If it's a really low buck deal a good oil will be alot cheaper than a cam swap to any roller set up. With a tight budget, probably just leave it alone and work harder on hitting the tree and the dial in.

Re: Hyd Roller SBC bracket drag car

In an 11 second bracket car there would be no reason to have a solid roller. The HR is perfectly capable of meeting your needs.

Re: Lighten an I - beam rod

Start by taking it off the typical balance areas, cap and pin end... beyond that it will get much more interesting.

Re: School me on 307 blocks

This is an interesting engine for sure. Do you want to share more information about the engine and the car setup ? I dont know any real specs. I do know that it has GM fastburn heads, an edelbrock 2925 intake, and a pretty mild hydraulic roller cam have not dug into the engine at all. It runs fine ...

Re: School me on 307 blocks

WHY ...? 4" bore blocks are plentiful and ruining a 3 7/8" bore block is not the thing to do in my opinion. If it is the engine I am thinking of, it was built by John Beck, not with just leftovers, and did quite well in that 1st contest pitting 366 maximum cube street engines. This is not "the" eng...

School me on 307 blocks

So I picked up this car last year and after doing some research I found out that it has a 397020 casting 307 with a 3.75 stroke crank. Kind of an oddball, but I guess it was built out of some leftovers from an Engine Masters deal around 2003. It is just a little 11 second footbrake bracket car at th...

Re: SB Mopar oiling mods

Drill a small hole through your thrust bearing into the back side of the block into the oil galley. Positive thrust oiling always made my trans brake equipped 360s very happy. I think it may be overkill for you but it wont hurt in high torque uphill situations.... just like a wheels up launch.
