Building an engine.

[ausername]

Hi folks,

I'm planning to build a new engine for my Marauder.
I'm looking for recommendations for a block to start with (seems like the place to start). What ones are compatible with 4v heads? Will a newer Vic block fit? I am on a budget so a new cast iron block is probably not what I want or need lol.

My goal is a solid engine that I can put a blower on and safely get 450hp at the wheel. Its a long term project so I have time to shop around and ask advice.

That being said I want to build a whole separate engine without scavenging parts off my existing engine.. plus then I couldn't drive my merc!

Thanks for any input.
Mike

Marauder block is aluminum not cast iron. Forged block is best for supercharge apps and forged rods, pistons, crank. But those are not budget minded. A stock marauder block is good for around 450 Rwhp so maybe rebuild a used marauder motor

You also have the option to use Ford's Boss 5.0 block. That could be stroked out to 5.3L if you wanted to also.

Boss 5.0 block is iron and will require machining, to get to 5.3L it has to be bored and stroked.

The cheapest route is to find a Teksid aluminum, just make sure it's not from a FWD Lincoln car.

Did you miss the part about him being on a budget? a BOSS short block after machining , and a rotating assembly is easily over 6K!

If you can find a Teksid block out of a 93-98 Lincoln Mark VIII, 96-98 Cobra. The lincoln mark VIII engines can be found pretty reasonable, 450 wheel hp is well within their capable range. On the plus side if you are able to find one from a cobra you will have a Forged Kellogg crank, still have to get forged rods and pistons.
Cast iron block wouldn't be horrible but why add weight.

Avoid Lincoln Continental blocks as they are FWD

03/04 Cobras had Forged cranks , rods , and pistons , not just cranks!

Right, I was speaking to the 96-98 cobras as he said he was on a budget. I guess if $6k-$8k is within budget maybe an 03-04 cobra swap would be the way to go. They are all over ebay.

I think they are still available - 2004 Cobra Reman Long Block from Ford - ~$5,300.

3-4 month backorder IIRC

Contact KC at BRG Racing. He is planning to re-build my stock 4.6 with all forged components. KC is installing my new motor, so the re-build stock engine may be the price you seek. Shipping costs will likely run $500 territory.

Wow lots of info.. sounds like a teksid is the way to go. Thanks for the tip Lowndex but the Canadian dollar is... not great right now lol .. I wanna get as much in Canada as I can. Was looking at some high mileage aviators.. they are cheap.. any reason not to buy one to pull the engine? Upside is I would get a set of heads in the deal too.

[RubberCtyRauder]

I might be wrong, I think aviator heads are possibly different in terms if performance. I think there is something about the heads. Someone with better info will hopefully reply. I wanna say something about a B or C head?

[rauder88]

Aviator would be a good choice. Will have C heads just like the marauder and has the same cams as us.
The heads and cams are the same for the 03/04 Cobra, Mach 1, Marauder and Aviator

Yep the long block is the same besides forged internals in the Cobra and forged crank in the Mach 1 with manual trans. The Aviator intake manifold/tb setup is just different, I believe it has a single 70mm TB. Not sure if the timing cover and oil pan is different though.

[RubberCtyRauder]

Good that heads are the same . I thought there was something but glad it is the ssne

[ausername]

Awesome.. so I'll keep my eyes out for a mark viii or an aviator. Any reason to avoid a higher mileage engine since I'm rebuilding it anyways? Planning to send the block to a shop for machining, sand blast, and possibly a powder coat, and have the heads rebuilt at a shop.. I've done a few engine rebuilds but never heads. Figure leave that one to the pros.

[Badass_forever]

Main Question is, How much are you willing to spend.


The blocks are all the same, you just put 2v, 3v or 4v heads on them. The build quality of the block is dependent on what you are doing.

I have an iron block in the garage that needs machining. come get it or its becoming a table soon.


best bet is to stick with what you already have, that way you don't have to chase down parts. I spent almost a full year chasing down parts to go from 2v to 4v swap for my mustang.

the heads are easier then the blocks, i have step by step pictures I could send you. The mileage on the block doesn't really matter as long as nothing went boom.

I'm also planing just like you, and of course the budget is kinda low, but why don't you use your block (the marauder block) and change the rods and pistions! I think the marauder block and the crank can handle the 450whp! please correct me guys if i'm wrong.

If your serious I might take you up on that offer. For sure I'd be interested in step by step on the heads.. I'll pm you my email. Its not that I don't have money to put in it.. I just want to be wise with the money.

This is more of a side project.. I want to drive the car while I start the build.

Oh, now I understand sorry for the missunderstanding! good luck with your project :)

No worries, good luck with yours too!
