bye bye thunderbird Reply #30 – January 19, 2012, 04:06:44 PM Persnally, I would have just slotted the motor mounts, kept the existing transmission, and swapped the sbc in the thunderbird. Whel someone finally makes the sbc head intake for the sbf I wouldn't have any issues with building one. Quote Selected

bye bye thunderbird Reply #34 – January 19, 2012, 08:51:41 PM i plan on accomplishing that feat sometime before summer, if time allows.. i'd like to run 1 of my 306's as the test motor for the combo, to see if it's really worth the effort.. should be with those massive flow #'sEDIT: also, headers will be a bit of an issue, as i see it.. because of the ford block design VS the GM block design.. LS headers may create a bit of an issue, because the #1 cyl is on the driver side, which is the reason the intake isn't useable.. not nearly as much as a fab headache, but definitely something that can't be brushed off, as it's likely to cause clearance issues without modification Quote Selected
bye bye thunderbird Reply #38 – January 19, 2012, 09:47:47 PM I would use a sbf because I have a block sitting at home with 14 miles on a rebuild. If I had $1k for a set of heads, I would just go aftermarket ford, and it wouldn't be an issue. The only problem with the 302 is the 2 bolt mains, but the block will split before the mains give out. As long as your under 500hp n\a, I don't see why you would need to use a sbc, especially considering you can have the same thing with a 351. Quote Selected
bye bye thunderbird Reply #39 – January 19, 2012, 10:07:34 PM why put a sbc in a ford and completely contradict the reason i built the sbf S10? plus, i don't care for the LS motors.. this is where you blab about how 'amazing' they are, but i don't give a rats A-double snakes.. it's the innovation and experimentation of the swap that intrigues me.. if the heads perform as well as statistics say, they should make a SBF quite the powerplant.. and did you get that quote from a bbf tech site, tom? if so, i read it to the end a while ago.. the guy who was supposedly 'building' the motor disappeared into thin air.. which means he was just blowing smoke up everyone's 'you know what' Quote Selected
bye bye thunderbird Reply #40 – January 19, 2012, 11:46:58 PM quoyeMax Chevy: We’d heard about World adapting LS1 heads on a Ford small-block. Is that true?BM: Yeah, we did it. That’s our new Man O’ War 10-degree aluminum casting. It’s basically LS7 architecture. If you look real close at the Chevy and the Ford they are mirror images. They share almost the same bolt pattern except that the intakes and exhausts are positioned opposite of one another. Quote Selected

bye bye thunderbird Reply #44 – January 20, 2012, 02:46:25 PM Because a sbc head would cost less then 1/4 of what an aftermarket sbf head costs. The sbf is done at 500 fwhp, and if it lives past that, its on borrowed time. That is no secret. The real problem is the intake. Supposedly the clevlend blocks deck height is close enough that you can adapt a ls1 intake. But I do not have a clevland block. I don't have a chevy block, and few if any people that would consider an ls swap would have one either.My entire post was referring to how similar the motors are. Pretending you had a 351, which are generally good for up to 800hp, and you could get the chevy heads to bolt on, then why go through the effort of swapping out the motor? Even a sbf distributor drops right in a ls motor with a truck intake. You don't even have to swap computers, wires, sensors, anything really if you were to look at it. Even the bellhousings are identiical, minus one bolt hole.Basically, imho, a 302/347 will do anything an ls motor will do for similar cost that an ls motor could, up to 500hp. Which is why there is no real reason to swap between the motors unless you want to make over 500hp.Hope that helps. Quote Selected
