Would the Lincoln y block be similar to the phase 2 heads our of Argentina? Which head would flow better ?

Does cast iron age? I found a windsor ford engine group on facebook. guy wants to know which block to use to make 800 whp with a single turbo. the latest production 302 was in 2000 I believe. never particularly strong it was advertised as a thin wall casting. even the best windsor block from 69/70 a...

The head is off and there's no flow? Clogged oil galley?

I found a set of cast iron trick flow heads from the early 90s. They were never put in service. They are bare castings. I believe they are set up for 1.94/1.6 valves with 8 mm stems. Should i use them on a street 392W or sell them and look for aluminum heads. I'm trying to build a hi10/ low 11 sec s...

First...why would you pay 800.00 got Ford link bar roller lifters. I sell American made lifters for 550.00 retain all day long. Second...why does a motor with link bar lifters need a retrofit roller? I did a quick google search for lifters and thats the price I found. Havent researched them properl...

Havent decided on any of that yet. Will a low use hot rod benefit enough to justify the cost

Good afternoon gentlemen. I'm bored silly during this pandemic and found some free parts on Facebook. I'm going to build this sbf for the street nothing radical just good street performance. Is it worth the cost to convert to hydraulic roller lifters? Is there enough performance gain to spend $800+ ...

4 valve heads with variable valve timing for the bbf.

Mn12 thunderbird or cougar. IRS. Comfy long distance cruiser. Stroker 4v 4.6 swap with twins and a 5 or 6 spd swap would be big fun.

The injector is usually mounted straight up. It may not be square but these injectors are mounted visibly canted toward the center of the engine not pointed to the intake valve at all. Will this make the engine more susceptible to build up on the intake valve? Or more susceptible to fuel pudding or ...

I saw a homemade fuel injection setup for a 390 ford using a 351c tunnel ram. The owner has the injectors tilted for clearance instead of square to the intake runner. Will this affect performance? Everyone I've ever seen including stock is square to the runner. Is there a reason?

how did grandma only get 12mpg in a 974.6 cougar? was the od turned off or was she driving in 2nd gear. i had one that got 30mpg on the highway and even at 200K miles was still good for low 20's. and you are replacing this car with an 85 cfi grand marquis?

Is the extra expense of a custom piston worth it in a stock stroke street 351w about 400hp?

thank you gentlemen.i was not relishing the idea of building two 351w just to find out. those things can get expensive in a hurry.

Hello gentlemen. ive been lurking here for a bit now and i have a question. if i build two engines identically except for rod length which will perform better? i mean they balance the same (rod and piston weights are equal) same ring package same compression ratio (identical piston shape and chamber...
