증상
쉐보레 307 엔진(캐스팅 번호 3970020)을 4인치로 보링하여 327으로 개조하려고 함. 307 헤드를 계속 사용할 수 있는지 확인 필요.
처리 내용
네, 307 헤드를 이 빌드에 사용할 수 있습니다. 다만 307 헤드의 한계를 이해해야 합니다. 모든 307 헤드는 1.72인치 흡기밸브가 장착되어 있으며, 이는 매우 작은 사이즈입니다. 반면 350은 대부분 1.94인치 흡기밸브가 있습니다. 307은 작은 사양으로 설계되었으므로 성능 향상의 한계가 있습니다. 327을 제대로 빌드하려면 350 엔진을 구입하고 크랭크를 교체하는 것이 훨씬 낫습니다. 완성된 350 엔진은 상대적으로 저렴하고 시장에 많습니다. 비용 절감이 주 목적이라면 350 Vortec 트럭 헤드를 구입하는 것이 좋은 선택입니다. 이 헤드들은 매우 흔하고 가격이 저렴하면서도 연소실 설계가 우수하고 흐름 특성이 우수합니다.

BMW M5
I started this thread really with a question about pros and cons of putting an AJP or something else in my scrap Cerbera and it has morphed into a project build thread over time. Brief history:I was thinking about buying myself a fun sports car, there's nothing new in the £50-80k range I would particularly be interested in. Had to feel special, had to be light, "analogue" and not overly-assisted. Had to be manual and i prefer a large capacity NA to forced induction. Ford Mustang maybe, perhaps not quite special enough and a bit porky. Emira - I love Lotus and have had a few but i'm not a fan o
BMW X5
After writing off my BMW 320d halfway through the month, I suddenly found myself in the market for a new car.Once the insurance payout landed, I had just under £5,500 to play with after paying my excess. I spent hours trawling AutoTrader trying to find the right replacement.I'd lined up a BMW X5 that was slightly over budget and was due to view it today... only for it to sell yesterday before I got the chance. Frustrating, but that's just how it goes.I kept looking, but nothing else really grabbed me.Then I spotted a Range Rover Sport on AutoTrader just five miles away. I called the dealership
