My powerplant is here!!!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1971ls1longbed · 06-04-2011, 08:44 AM

well after saving all my extra money i finally got my engine delivered. Its a 454 .030 over, forged bottom end, flat top pistons, 9.25:1 compression, revalved ported and polished 781 heads, and studed. i know the studs are overkill but thats the way it was assembled by the previous owner.

Actually with the shipping from Foley MN it was $2000 and i got a balancer and a really good timing set. I am super amped to get this thing fired up. next week i am sending out the money for the carb and roller rockers from the same guy.

weaintscared · 06-04-2011, 01:21 PM

I bought almost everything for mine new forged dome pistons,all ARP Bolts,inside & outside the motor 554 cam roller rockers 850 proform carb & intake,new balancer,3/8 pushrod from Comp,all new alum pulleys and timing cover

bigboybodry · 06-04-2011, 02:42 PM

keep us posted I would like to see what they run. take some time in choosing a cam for what you are going to be doing with the (street/strip etc...) truck that's were the power is. I hate not being able to drive mine back and forth to work/weekends slaying mustangs and camaros.

Super73 · 06-04-2011, 03:13 PM

Good luck with the new build!! Hope it runs like you want it too..

I remember when you were selling off your LS parts.. You going to do a name change?

I will definitely take your advice about the cam and keep everyone posted on whats up with the engine. First I want to get the heads flowed so I get the right cam for a hot street/strip truck

Gotta love oval port big blocks! Also, if you're gonna go though the trouble to get the heads flowed and pick a cam, are you getting a custom cam? If so, I will recommend Chris Straub (www.straubtechnologies.com). You can check his work out over on www.chevelles.com in the 'performance' section. He cut me a roller cam for my 468, and really knows his stuff, especially when it comes to street/strip BBC's.

I absolutely am going to get a custom cam. i want to maximize hp and tq and i do feel that an off the shelf cam wont do that. And thanks for the link i will definitely check out his website

djracer · 06-07-2011, 11:05 PM

Good luck with the build! I have a similar motor for my son's truck. Personally I wouldn't flow the heads or get a custom cam. I think your money could be spent better elsewhere.

weaintscared · 06-10-2011, 01:06 PM

here's my builb if you wanna take a look

m6z · 06-21-2011, 09:58 AM

sounds like a solid 500+ combo.

1971ls1longbed · 06-30-2011, 05:30 PM

I just got my Hooker Super Comp headers from 70shortwide. These things are awesome. I also got my fuel system and ill post pics tomorrow

1971ls1longbed · 06-30-2011, 06:07 PM

If anyone can help im also looking for a tall deck 427 block

BossHogg69 · 06-30-2011, 07:13 PM

Who ended up doing your cam for you? Specs above look like a Comp Cams grind.

As for a hp guess, I'll say 530hp @ 5500 and 550tq @ 4300
