Late Model Engine recommendation

[powerslide]

we will be running on a big 5/8 mile real slick momentum track . iron block . a head , bore / stroke combo would be greatly appreciated . Any thoughts perf conn ???

Honestly it depends what the competition is like. Our local late model class has 8-10 cars. Not a lot of big budget guys and you can compete on a big 3/8 with a 406 w/ 23 degree heads pushing 750hp, the mods at the same track are probably running similar motors. But like tony and perf have mentioned if you have guys running the wide bore motors it will be tough to compete. A set of good -12's, 18 degree, or sb2.2 are all going to put you in the good at most local tracks.

When trucks were running Pro Stock, with SB2.2 heads, or similar, with 2 dominators, they made around 950.
Making that much with 23 degree heads??? I seriously doubt it. TB

I know Chris U. well and I don't recollect him ever saying he made 950hp w/23* all pros without using power adders.

"Bought my first set of All Pro's and won a bunch of races. Built many, many All Pro 23 degree engines.... last one made 960 hp single 4 cast intake."

Its in the NA section so I assumed it was NA. I understand that is not the norm and it is basically a 18 or 13 casting with the valves installed at 23 degree so the average dirt track guy isn't going to get anywhere near that and they probably had more in the heads/top end than he would if he bought a used 18 degree set and built a whole 18degree motor.

OK,he did say it.I would like for him to put that engine in a dirt latemodel and try to get it off the corners at 4500rpm.We are talking dirt track here not 11,000 rpm 5 speed drag racing.Big difference.

Big difference! The difference between night and day for sure.

18 degree engines still win their share of local races but are fading fast.

I'd get a good 13 degree setup and learn how to hook it up and then go for broke if the pocket book allows.

Terry , what do you think of the old 14 degree pro action head ? 230cc on alcohol ?

[perfconn]

14* aluminum or steel?The 14* aluminum head won't make the power of a good 13* or 11* or SB2.2 but on a local level they can be competetive.14* steel head is best steel head ever made but very heavy.

Late model engine

We are starting to look into getting ready to make an up grade to late model, I hear about these 9,11,14,18 degree aluminium engines. My question is which would be the best all around motor, right now we run a 3/8 high banked oval ( you know the conditions dry when hot, wet tacky when cool & everything in between) I can only afford to do this investment once plus of course keep maintained.Thank you in advance

I have several customers that win consistenly in Supers with all steel 360ci but they get a 12" spoiler & the big all aluminum engines only get 8" spoilers.This is on local weekend racing not Lucas or WoO.If you want to compete on the Lucas then you better have two cars,stacker trailer,at least 3 all aluminum engines in the 430-460ci range and lots of money.

I think the 18 degree with an alum block would be a minimum in that area of the country. 13 degree or sb2 or something on top of a wide bore block would be better. Call one of the big motor builders and see what they have to offer.
